Iminium‐Ion Activation as an Efficient Strategy for Divergent Synthesis of Optically Active Propargylic, Homopropargylic, and Allenic Compounds

Abstract

Assemble and build: The strategy depicted above merges different organocatalyzed conjugate addition reactions with the Seyferth–Gilmann homologation by which diverse optically active propargylic, homopropargylic and allenic products can be assembled in high yields and enantioselectivities.
