Sulfinylimidates as Chiral Amide Equivalents for Irreversible, Asymmetric Aldol Reactions

Abstract

A highly selective N-sulfinylimidate aldolization has been developed under mildly basic conditions leading to diastereopure products of high synthetic potential. The innate reversibility of this aldolization was suppressed by the use of titanium as the Lewis acid. An application of this methodology via the synthesis of a potential neurotransmitter reuptake inhibitor is illustrated.
