A One-Pot Process for the Enantioselective Synthesis of Amines via Reductive Amination under Transfer Hydrogenation Conditions
摘要:
Cyclic amines may be prepared via a sequence of deprotection followed by intramolecular reductive amination of t-Boc-protected amino ketones under asymmetric transfer hydrogenation conditions. In cases where the corresponding imine reaction proceeds with high enantioselectivity, this is reflected in the one-step process.

enantioselectivity via the conjugate addition of cyclic amines to unactivated α,β-unsaturated esters. A related strategy enables the kineticresolution of racemic cyclic 2-arylamines, using benzyl acrylate as the resolving agent. Reactions are facilitated by an unprecedented selenourea-thiourea organocatalyst. As elucidated by DFT calculations and 13C kinetic isotope effects studies, the rate-limiting and enantiodetermining

novel amineoxidase (AO)/iminereductase (IRED) system was developed for the deracemization of racemic amines. By combining (R)‐6‐hydroxy‐d‐nicotine oxidase (6‐HDNO) with an (R)‐IRED, a panel of racemic 2‐substituted piperidines and pyrrolidines were deracemized to yield the (S)‐amines in high yields and enantiomeric excess values. Other N‐heterocycles were deracemized with monoamine oxidase (MAO‐N)
