Recently I am researching about MOLECULAR-ORBITAL METHODS; FORCE-FIELD PARAMETERS; ASYMMETRIC-SYNTHESIS; KINETIC RESOLUTION; ENANTIOSELECTIVE ALLYLATION; CYCLOBUTANE BACKBONE; MODULAR LIGANDS; BASIS-SETS; AB-INITIO; ALKYLATION, Saw an article supported by the Spanish Ministry of Economy and Competitiveness [CTQ2016-74878-P]; European Regional Development Fund (AEI/FEDER, UE); Catalan Government [2017SGR1472]; ICREA Foundation (ICREA Academia award). Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Biosca, M; Salto, J; Magre, M; Norrby, PO; Pamies, O; Dieguez, M. The CAS is 91-00-9. Through research, I have a further understanding and discovery of Diphenylmethanamine. SDS of cas: 91-00-9
A method for generation of Pd/phosphite-oxazoline catalysts containing an alkyl backbone chain has been successfully applied to Pd-catalyzed allylic substitution reactions. By carefully selecting the substituents at both the alkyl backbone chain and the oxazoline of the ligand, as well as the configuration of the biaryl phosphite group, high activities (TOF > 8000 mol substrate X (mol Pd X h)(-1)) and excellent enantioselectivities (ee’s up to 99%) have been achieved for many hindered and unhindered substrates with a wide range of C-, O-, and N-nucleophiles (73 substitution products in total). Moreover, DFT and NMR studies of the key Pd-allyl complexes allowed us to better understand the origin of the excellent enantioselectivities observed experimentally. The useful application of the Pd/phosphite-oxazoline catalysts was demonstrated by the syntheses of many chiral carbobicycles, with multiples stereocenters, by simple sequential reactions involving Pd-allylic substitution and either 1,6-enyne cyclization or Pauson-Khand enyne cyclization.
