摘　　要：糖类在很多生命活动中发挥着重要的作用,例如细胞壁组成、能量储存以及生物识别等.发展高区域选择性和立体选择性的糖基化反应是目前糖化学研究的中心问题.传统的化学糖基化方法往往需要依靠正交的保护基化学来调控糖基化反应的选择性.近年来一些无保护糖基化的策略被开发出来,可以在更简单、更温和的条件下实现寡糖及其缀合物的选择性合成.对近期发展的无保护糖基化策略进行了综述,并对无保护糖基化反应的未来发展前景进行展望.Carbohydrates play a key role in many life activities,such as cell wall composition,energy storage and biological recognition.Development of highly regio-and stereo-selective glycosylation reactions is a central topic of current carbohydrate chemistry.The traditional glycosylation protocol usually requires the orthogonal protecting chemistry to obtain the selectivity of glycosylation reactions.Recent progress in protecting-group free strategies can provide a simple and mild approach to the chemo-selective construction of glycosidic bonds in oligosaccharides or glycoconjugates in aqueous conditions.The latest advances in protection-free chemical glycosylations are summarized,including the direct anomeric activation strategy developed by our group.
