摘要: A modular synthesis of cyclohexenones is described and applied to the first enantioselective total syntheses (+)-crypto- (+)-infectocaryone. Key steps in are an iridium-catalyzed allylic alkylation, nucleophilic allylation, ring-closing metathesis. On way (+)-cryptocaryone, a catch release strategy involving iodolactonization/elimination regioselective C-acylation were used.
