摘要

A mild step and atom-economical nonepimerizing chemo-and enantioselective N-alkylating procedure has been developed via oxidation/imine–iminium formation/reduction cascade using TEMPO–BAIB–HEH–Brønsted acid catalysis in DMPU as solvent and a stoichiometric amount of amine. The optimized conditions were further extended for the nonenzymatic kinetic resolution of the chiral amine thus formed under nonenzymatic in situ hydrogen- ...
