Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Goerke, Steffen, once mentioned the application of 1638767-25-5, Name is tert-Butyl (3-aminobicyclo[1.1.1]pentan-1-yl)carbamate, molecular formula is C10H18N2O2, molecular weight is 198.2621, MDL number is MFCD27987307, category is amides-buliding-blocks. Now introduce a scientific discovery about this category, Formula: C10H18N2O2.
Synthesis and anion recognition studies of new oligomethylene bis(nitrophenylureylbenzamide) receptors
A new series of oligomethylene bis(nitrophenylureylbenzamide) receptors were synthesized varying the relative position of the urea and amide groups (ortho4 and meta8) and the length of the oligomethylene chain (C-2 to C-8). An anion recognition study was performed with TBAX salts (X = AcO-, BzO(-), F-, H2PO4-, and HP2O73-) by UV-vis and H-1 NMR. The flexibility of these receptors allows a cooperative effect of both ureylbenzamide units in the receptors. Noteworthy, the ortho position favored the 1 : 1 stoichiometry in the complexes with the carboxylates. The formation of 2 : 1 receptor-anion complexes with both types of receptors 4 and 8 and with hydrogen pyrophosphate and high log K values obtained were very significant in this work. The NMR studies evidenced the formation of supramolecular complexes, even in a competitive solvent, such as DMSO.
