Stereoselective Sulfinyl Aniline-Promoted Pd-Catalyzed C-H Arylation and Acetoxylation of Aliphatic Amides

Stereoselective functionalization of aliphatic C-H bonds presents a great challenge. Following this target, we disclose herein an original strategy towards direct arylation of aliphatic chains at ss-methylene position based on a use of amide-sulfoxide bicoordinating directing group. Although moderate to high chiral induction (up to 9:1d.r.) is achieved, diastereomerically pure compounds may be afforded by simple separation of diastereomeric products by silica gel chromatography. Accordingly, this reaction allows preparation of a large scope of high-value scaffolds in synthetically useful yields while recyclable character of our chiral auxiliary brings an additional benefit. A potential of this methodology to build up original molecules by sequential diarylation and expedient (two step) synthesis of a biologically active compound are further disclosed. Finally a first example of stereoselective direct acetoxylation of aliphatic chains is reported.

How to Contribute to the Progress of Neuroendocrinology: Discovery of GnIH and Progress of GnIH Research

It is essential to discover novel neuropeptides that regulate the functions of pituitary, brain and peripheral secretory glands for the progress of neuroendocrinology. Gonadotropin-releasing hormone (GnRH), a hypothalamic neuropeptide stimulating gonadotropin release was isolated and its structure was determined by Schally’s and Guillemin’s groups at the beginning of the 1970s. It was subsequently shown that GnRH is highly conserved among vertebrates. GnRH was assumed the sole hypothalamic neuropeptide that regulates gonadotropin release in vertebrates based on extensive studies of GnRH over the following three decades. However, in 2000, Tsutsui’s group isolated and determined the structure of a novel hypothalamic neuropeptide, which inhibits gonadotropin release, in quail, an avian species, and named it gonadotropin-inhibitory hormone (GnIH). Following studies by Tsutsui’s group demonstrated that GnIH is highly conserved among vertebrates, from humans to agnathans, and acts as a key neuropeptide inhibiting reproduction. Intensive research on GnIH demonstrated that GnIH inhibits gonadotropin synthesis and release by acting on gonadotropes and GnRH neurons via GPR147 in birds and mammals. Fish GnIH also regulates gonadotropin release according to its reproductive condition, indicating the conserved role of GnIH in the regulation of the hypothalamic-pituitary-gonadal (HPG) axis in vertebrates. Therefore, we can now say that GnRH is not the only hypothalamic neuropeptide controlling vertebrate reproduction. In addition, recent studies by Tsutsui’s group demonstrated that GnIH acts in the brain to regulate behaviors, including reproductive behavior. The 18 years of GnIH research with leading laboratories in the world have significantly advanced our knowledge of the neuroendocrine control mechanism of reproductive physiology and behavior as well as interactions of the HPG, hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid axes. This review describes how GnIH was discovered and GnIH research progressed in this new research era of reproductive neuroendocrinology.

Hydrogen Bond-Directed Formation of Stiff Polymer Films Using Naturally Occurring Polyphenols

Although coatings cast from waterborne polymer dispersions are significantly more environmentally friendly than their solvent-based counterparts, their relatively poor mechanical properties limit their use. In this work, mechanically reinforced polymer films from waterborne dispersions are presented in which the stiffness is provided by the hydrogen bond-directed formation of a honeycomb microstructure. Blends of an acrylic copolymer latex containing a hydrogen bond accepting pyrrolidone group and tannic acid, a naturally occurring H-bond donating polyphenol, lead to a cellular structure with physically cross-linked tannic acid forming the cell walls and the acrylic polymer occupying the space inside the cell walls. It is demonstrated that the formation of the honeycomb microstructure was promoted by H-bond interactions and led to materials with greater mechanical performance. Furthermore, we show that the high strength of the phenol-amide interaction allows these mechanical properties to be retained even after extensive exposure to water. This approach opens the way to replacement of solventborne polymers in many applications that require hard polymer films.

System map for the ionic liquid stationary phase tri(tripropylphosphoniumhexanamido)triethylamine bis(trifluoromethylsulfonyl)imide for gas chromatography

The solvation parameter model is used to construct a system map for the retention of volatile organic compounds on the ionic liquid stationary phase tri(tripropypphosphoniumhexanamido)triethylamine bis(trifluoromethylsulfonyl)imide (SLB-IL76) over the temperature range 80-240 degrees C. The SLB-IL76 stationary phase is moderately cohesive and strongly dipolar/polarizable and hydrogen-bond basic but only a weak hydrogen-bond acid. Electron lone pair interactions are weak and make only a minor contribution to the retention mechanism. The separation properties of SLB-IL76 highlight the difficulty of designing new stationary phases from ion structures as the presence of amide groups in the cation don’t seem to contribute significantly to the hydrogen-bond acidity of SLB-IL76. The separation properties of SLB-IL76 are closest to the bis(polycyanopropyl)siloxane stationary phases with a high percentage of bis(cyanopropyl)siloxane monomer and could be used in method development when a stationary phase with similar gross retention characteristics but different selectivity is required.

n ->pi* Interactions Modulate the Properties of Cysteine Residues and Disulfide Bonds in Proteins

Noncovalent interactions are ubiquitous in biology, taking on roles that include stabilizing the conformation of and assembling biomolecules, and providing an optimal environment for enzymatic catalysis. Here, we describe a noncovalent interaction that engages the sulfur atoms of cysteine residues and disulfide bonds in proteins-their donation of electron density into an antibonding orbital of proximal amide carbonyl groups. This n ->pi* interaction tunes the reactivity of the CXXC motif, which is the critical feature of thioredoxin and other enzymes involved in redox homeostasis. In particular, an n ->pi* interaction lowers the pK(a) value of the N-terminal cysteine residue of the motif, which is the nucleophile that initiates catalysis. In addition, the interplay between disulfide n ->pi* interactions and C5 hydrogen bonds leads to hyperstable beta-strands. Finally, n ->pi* interactions stabilize vicinal disulfide bonds, which are naturally diverse in function. These previously unappreciated n ->pi* interactions are strong and underlie the ability of cysteine residues and disulfide bonds to engage in the structure and function of proteins.

Comparison of the physicochemical and electrochemical behaviour of mixed anion phosphonium based OIPCs electrolytes for sodium batteries

The physicochemical properties of the phosphonium-based organic ionic plastic crystal (OIPC), triisobutylmethylphosphonium bis(fluorosulfonyl)amide (P1i444FSI) in mixtures with sodium salts consisting of different anion structures, sodium bis(fluorosulfonyl)amide (NaFSI), sodium bis(trifluromethanesulfonyl)amide (NaNTf2) and sodium hexafluorophosphate (NaPF6) were investigated. The phase behaviour, ionic conductivity and electrochemical performance at a sodium concentration of 20 mol% for each anion system were compared. 20 mol% P1i444FSI/NaPF6 displays complicated phase behaviour with additional phase transitions and a higher melting temperature compared to pure P1i444FSI, indicating the formation of a new compound which is different from pure P1i444FSI or NaPF6. The system consisting of 20 mol% NaNTf2 exists as a supercooled liquid across the whole temperature range with a glass transition at -73 degrees C. At temperatures corresponding to their liquid state, the ionic conductivity values for both 20 mol% NaFSI and NaNTf2 systems are substantially higher than the NaPF6 system and are approximately similar. Na symmetrical cell cycling at room temperature and 50 degrees C for these two systems at current densities of 0.1 and 0.25 mA cm(-2) exhibited stable and reversible sodium stripping and plating behaviour with very low polarisation potentials. In contrast, for cells based on the 20 mol% NaPF6 electrolyte, an extended time or higher current density is required in order to form a stable SEI layer before stable cell polarisation behaviour is reached.

N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study

The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was evaluated by using the Kamlet-Taft solvent parameter set, i.e. applying linear solvation energy relationships (LSER) principles. Optimized geometries and experimental results were interpreted by using DFT (B3LYP/6-311+G(d,p) method) and time-dependent density functional (TD-DFT) method. Overall electron density in both ground and excited state was obtained by the use of Quantum Theory of Atoms in Molecules, i.e. Bader’s analysis. It was found that both solvent and substituents cause appropriate change of the extent of conjugation in the molecules that further affect their intra-molecular charge transfer (ICT) character. Linear free energy relationships (LFERs) were applied to the substituent-induced NMR chemical shifts (SCS) using single substituent parameter (SSP) and dual substituent parameter (DSP) model. Transmission mode of the electronic effects of substituent was discussed according to the results of theoretical calculations and results of LFER correlations. Comparative analysis of presented results with the ones published for structurally similar series of amide which contained cyano group, instead chlorine, provides additional information on the impact of present group to the properties of investigated compound.

Direct Lewis Acid Catalyzed Conversion of Enantioenriched N-Acyloxazolidinones to Chiral Esters, Amides, and Acids

The identification of Yb(OTf)(3) through a multivariable high-throughput experimentation strategy has enabled a unified protocol for the direct conversion of enantioenriched N-acyloxazolidinones to the corresponding chiral esters, amides, and carboxylic acids. This straightforward and catalytic method has shown remarkable chemoselectivity for substitution at the acyclic N-acyl carbonyl for a diverse array of N-acyloxazolidinone substrates. The ionic radius of the Lewis acid catalyst was demonstrated as a key driver of catalyst performance that led to the identification of a robust and scalable esterification of a pharmaceutical intermediate using catalytic Y(OTf)(3).
