A short stereoselective synthesis of (+)-(6R,2'S)-cryptocaryalactone was successfully completed. Key steps included the application of Carreira's asymmetric alkynylation reaction to form a propargylic alcohol and subsequently lactone formation using the powerful ring-closing metathesis reaction.
(+)-(6R,2'S)-cryptocaryalactone 的短立体选择性合成成功完成。关键步骤包括应用 Carreira 的不对称炔基化反应形成炔丙醇,随后使用强大的闭环复分解反应形成内酯。
