Abstract
A new strategy to access highly enantioenriched cyclic compounds (up to 98%) is proposed using omega-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.
摘要
提出了一种新策略，通过一锅不对称烯丙基烷基化和环化复分解反应，使用ω-烯丙基烯丙基底物来获得高对映体富集的环状化合物（高达 98%）。这种起始化合物可以被视为环状烯丙基底物的合成等价物。
