本文综述了近年来糖基化反应的研究进展,并着重介绍了糖基化反应的机理。越来越多的证据,糖基oxocarbenium离子的存在,在一些反应中作为短暂的中间体,以及在其他相关的反离子的关键作用进行了讨论。用于糖基化反应的SN1和SN2歧管的极端由连续的机制桥接,其中似乎可能存在大多数实例。
An overview of recent advances in glycosylation with particular emphasis on mechanism is presented. The mounting evidence for both the existence of glycosyl oxocarbenium ions as fleeting intermediates in some reactions, and the crucial role of the associated in counter ion in others is discussed. The extremes of the SN1 and SN2 manifolds for the glycosylation reaction are bridged by a continuum of mechanisms in which it appears likely that most examples are located.
