摘要

Optically active trans-N-Boc-cyclopentane-and cyclohexane-1, 2-diamines (7) were prepared by a chemoenzymatic method from the corresponding (±)-trans-N, N- diallylcycloalkane-1, 2-diamine. These mono-carbamates 7 (ee= 99%) were used as the starting materials in the syntheses of different vicinal primary–tertiary diamines. Thus, by means of a simple three-step sequence involving a reductive-amination of an aromatic ...
