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 oxidative ring 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.
连续四元碳中心的立体有择构建构成了
天然产物合成的主要挑战。使这种部分的所有立体异构体的立体特异性构建成为可能的通用协议仍然难以捉摸。在本文中,我们将讨论由
H2O2 介导的全取代环状 α-甲酰基酮的氧化环收缩,这为连续季碳中心的立体有择构建提供了便利。
