A novel enantioselective copper-catalyzed trifluoromethylalkynylation of styrenes, proceeding through a radical relay process, is described herein, which affords structurally diverse CF3-containing propargylic compounds in good yield with excellent enantioselectivities under very mild conditions. In addition, the reaction features wide substrate scope and good functional group tolerance. Moreover,
本文描述了通过自由基中继过程进行的苯乙烯的新型对映选择性铜催化三氟甲基炔基化,其在非常温和的条件下以良好的收率和优异的对映选择性提供结构多样的含 CF3 炔丙基化合物。此外,该反应底物范围广,官能团耐受性好。此外,三氟甲基炔基化产物可以很容易地转化为合成有用的手性末端炔烃、丙二烯、Z-烯烃以及CF3修饰的非甾体抗炎药。
