主讲内容简介:

The polarity reversal of classical functional groups offers a powerful yet underexplored strategy in synthesis, enabling disconnections that bypass the constraints of traditional two-electron pathways. A striking example lies in heteroatom-stabilized allylic anions, which act as ambident nucleophiles and can serve as acyl anions or homoenolate equivalents. Despite their conceptual appeal, practical application has been hindered by longstanding issues with regioselectivity and the near-total absence of stereocontrol. This presentation will highlight our recent development of enantioselective reactions that construct allylic and homoallylic acyclic tertiary and quaternary stereogenic centers in complex bioactive molecules. Our approach merges a highly conserved enantioselective transformation with a stereospecific rearrangement, enabling the precise relay of stereochemistry to a remote site. These advances unlock streamlined access to elusive acyclic remote stereocenters, revealing new frontiers for polarity-reversed nucleophiles in asymmetric synthesis.
