established via a preactivation-based, additive-modulated trichloroacetimidate glycosidation strategy. The current protocol is mild, practical, and successful with various xylopyranosyl donors and glycosyl acceptors, including acceptors that are reported to be less reactive due to steric hindrance. The utility of this method was demonstrated with the facile assembly of matriglycan constituent tetra- and
通过基于预激活、加成调节的三氯乙酰亚胺酯糖苷化策略,建立了 1,2-顺式-吡喃木糖苷键形成的高度立体选择性策略。目前的方案温和、实用,并且对各种吡喃木糖基供体和糖基受体成功,包括据报道由于空间位阻而反应性较低的受体。通过基质聚糖成分四糖和六糖的轻松组装证明了该方法的实用性。
