Web1 nov. 2024 · Due to mild reaction conditions and environmentally friendly processes, biocatalysis is a promising alternative strategy for the synthesis of chiral amines [7, 8]. Especially, the reductive amination of carbonyl compounds and amines represents a simple and direct method for accessing amines.

The hydrogenation of ketones and imines with C=X (X=N, O) polar double bonds catalyzed by transition-metal complexes is an important synthetic method to produce value-added alcohol and amine chemicals in organic … WebThe most interesting application is as a borane source for oxazeborolidine catalyzed asymmetric reductions of ketones ( Corey-Bakshi-Shibata Reduction ). Very interesting is also the direct reduction of carboxylic acids to alcohols (BMS) and amides to amines (BTHF). The presence of complexing groups sometimes leads to borane adducts. todd wilson red robin
