NHC-Ni catalyzed enantioselective synthesis of 1,4-dienes by cross-hydroalkenylation of cyclic 1,3-dienes and heterosubstituted terminal olefins

Abstract

Chiral 1,4-dienes are versatile building blocks in asymmetric synthesis, therefore their production is highly sought after. Here, the authors report an efficient enantioselective cross-hydroalkenylation of cyclic 1,3-dienes and terminal olefins affording chiral 1,4-dienes by using a chiral NHC-Ni(allyl)]BArF catalyst.
