Bacterial Preparation of Enantiopure Unactivated Aziridine-2-carboxamides and Their Transformation into Enantiopure Nonnatural Amino Acids and vic-Diamines

Abstract
[reaction: see text] Enantiopure (1R,2S)-1-benzyl- and 1-arylaziridine-2-carboxamides were obtained by kinetic resolution of their racemates by Rhodococcus rhodochrous IFO 15564 catalyzed hydrolysis. Several regio- and enantioselective nucleophilic ring openings of (1R,2S)-1-benzylaziridine-2-carboxamide or its LAH-reduced product led to a series of enantiopure products, such as O-methyl-l-serine and some vicinal diamines.
