Enantiodivergent, catalytic asymmetric synthesis of gamma-amino vinyl sulfones.
A set of diversely substituted N-Boc-gamma-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 alpha-amino acids as starting materials, is noteworthy for its efficiency, for its generality, and for the fact that both enantiomers of a given gamma-amino vinyl sulfone can be obtained with equal ease.
