A mild glycosylation protocol is developed by using glycosyl 1-methylimidazole-2-carboxylates. Such a glycosylation can be promoted by a series of metal triflates and triflimides, especially Cu(OTf)2. The reaction is initiated by activation of

A simple and versatile glycosylation method with both armed and disarmed glycosyl ynenoates as donors is developed. Employing a gold(I) complex as catalyst with or without the assistance of TfOH, the scope of the present glycosylation protocol is very wid
ortho-(Methyltosylaminoethynyl)benzyl glycosides as new glycosyl donors for latent-active glycosylation
Chen, Xiaoping,Shen, Dacheng,Wang, Qiaoling,Yang, You,Yu, Biao
, p. 13957 - 13960 (2015/09/07)
A new glycosylation protocol employing ortho-(methyltosylaminoethynyl)benzyl glycosides as glycosyl donors and TMSOTf as the catalyst is disclosed. These donors can be readily prepared from the corresponding 'latent' ortho-iodobenzyl glycosides via a Sonogashira coupling, thus providing a new approach for the 'latent-active' synthesis of glycans.
Bromodimethylsulfonium bromide/silver triflate-promoted glycosylations using glycosyl allenoates as donors

A series of novel glycosyl allenoates were prepared by condensions of hemiacetals with 3,3-dimethyl-4,5-allenoic acid. Their glycosylations with various alcohols under the promotion of bromodimethylsulfonium bromide/silver triflate smoothly proceeded to produce disaccharides. Studies reveal that allenic group is crucial for the efficient glylcosylation of glycosyl allenoate.
