A rhodium(III)-catalyzed C–H direct allylation reaction with 4-vinyl-1,3-dioxolan-2-ones has been developed. The reaction provides a facile and stereoselective access to substituted-(E)-allylic alcohols under mild and redox-neutral reaction conditions. Olefinic C–H activation is applicable, giving multifunctionalized skipped dienes in good yields. Minimal double-bond migration was observed.
已经开发了铑(III)催化的与4-乙烯基-1,3-二氧戊环-2-酮进行的C–H直接烯丙基化反应。在温和的和氧化还原中性的反应条件下,该反应提供了对取代的-(E)-烯丙基醇的容易和立体选择。可使用烯烃C–H活化,以高收率获得多功能的跳过二烯。观察到最小的双键迁移。
