product synthesis. A general protocol that enables stereospecific construction of all stereoisomers of such a moiety remains elusive. In this article, we will discuss the oxidativering contraction of all-substituted cyclic α-formyl ketones mediated by H2O2, which provides a facile access to the stereospecific construction of contiguous quaternary carbon centers.
ketones was facilitated by the action of H2O2 under operationally simple and environmentally benign reaction conditions. The process was highly regioselective and enables stereospecific construction of contiguous quaternary all‐carbon centers from stereodefined all‐substituted all‐cyclic ketones. The asymmetric syntheses of (+)‐cuparene and (+)‐tochuinyl acetate were also successively achieved by taking advantage
在操作简单和环境友好的反应条件下,H 2 O 2的作用促进了环状α-甲酰基酮的氧化环收缩。该过程具有高度的区域选择性,并能够从立体定义的全取代的全环酮立体构筑连续的季碳全碳中心。利用该新方案还成功实现了(+)-cuparene和(+)-tochuinyl乙酸酯的不对称合成。
