Enantiodivergent, catalytic asymmetric synthesis of γ-amino vinyl sulfones

A set of diversely substituted N-Boc-γ-amino vinyl sulfones has been prepared by a four-step procedure from readily available, highly enantiopure anti-N-Boc-3-amino-1,2-alkanediols. This new route, which does not depend on the accessibility of α-amino acids as starting materials, is noteworthy for its efficiency, for its generality, and for the fact that both enantiomers of a given γ-amino vinyl sulfone can be obtained with equal ease.
A short enantioselective synthesis of N-Boc-α-amino acids from epoxy alcohols
Poch, Marta
, p. 7781 - 7784 (2007/10/02)
A new and efficient enantioselective synthesis of Boc-α-amino acids has been developed. Starting from an enantiomerically enriched epoxy alcohol the sequence involves a regioselective nucleophilic epoxide opening by diphenylmethylamine (benzhydrilamine), hydrogenolysis/ protection of the amino group, and oxidation of the diol moiety.
