promote intramolecular conjugate additions of alkyl halides onto alpha,beta-unsaturated lactones. This process has been shown to be applicable to a number of alpha,beta-unsaturated lactones, including tetrasubstituted olefins, and has been demonstrated to be quite general for the formation of saturated bicyclic and tricyclic lactones. The method presented herein provides a mild, efficient process to form
在催化量的碘化镍(II)的存在下,碘化II(II)已用于促进烷基卤化物分子内共轭加成到α,β-不饱和内酯上。已经表明该方法适用于许多α,β-不饱和内酯,包括四取代的烯烃,并且已经证明对于形成饱和的双环和三环内酯是相当普遍的。本文提出的方法提供了一种温和,有效的方法,以从简单的前体形成结构复杂的内酯。
