A new strategy to access highly enantioenriched cyclic compounds (up to 98%) is proposed using ω-ethylenic allylic substrates through a one-pot asymmetric allylic alkylation and ring-closing metathesis. Such starting compounds can be seen as synthetic equivalents of cyclic allylic substrates.
提出了一种新的策略来获得高度对映体富集的环状化合物(高达98%),该方法使用ω-乙烯烯丙基烯丙基底物通过一锅不对称烯丙基烯丙基烷基化和闭环复分解反应。此类起始化合物可视为环状烯丙基底物的合成等同物。
