摘要

The synthesis of heterocyclic molecules is of increasing interest due to the many important biological properties of such compounds. Herein we introduce a new, concise, convergent, and highly stereocontrolled approach to certain types of heterocycles which involves only three steps from readily available precursors:(a) condensation of an aldehyde or ketone with a heteroatom-substituted carboxylic acid;(b) titaniummediated carbonyl olefination; and (c) ...
