Total syntheses of (+)-norsecurinine and (+)-allonorsecurinine are described that utilize a rhodium carbenoid-initiated O–H insertion/Claisen rearrangement/1,2-allyl migration domino process for the stereoselective introduction of the tertiary alcohol moiety. Overall the employed strategy is flexible and will allow access to other members of the Securinega family of alkaloids.
(+)-norsecurinine 和 (+)-allonorsecurinine 的全合成描述了利用铑卡宾启动的 O-H 插入/Claisen 重排/1,2-烯丙基迁移多米诺过程来立体选择性地引入叔醇部分。总体而言,所采用的策略是灵活的,将允许访问Securinega生物碱家族的其他成员。
