An efficient strategy for the totalsynthesis of (+)-przewalskin B is reported. The key steps feature an intermolecular SN2′ substitution of iodoallylic phosphate with organocupper reagent, a diastereoselective organocatalytic aldol cyclization, as well as a Rh2(OAc)4-mediated intramolecular carbene insertion to the tertiary C–H bond.
报告了一种有效的全合成(+)-przewalskin B的策略。关键步骤包括用有机铜试剂对碘代烯丙基磷酸酯进行分子间S N 2'取代,非对映选择性有机催化醛醇缩环化,以及Rh 2(OAc)4介导的分子内卡宾插入叔C–H键。
