Glycosyl donors, relative reactivities

Routes to Relative Reactivity Data Relative reactivity relationships describe the ratio of products between two glycosyl donors for an acceptor. Ley first constructed such relationships for fully protected mannoside and rhamnoside donors to rationalize the results of his one-pot syntheses employing cyclic diketals.16... [Pg.226]

Develop ways to determine the relative reactivity of glycosyl donors by calculation only and similarly to rank the reactivity of the hydroxyl groups of glycosyl acceptors. The ultimate goal would be to find unreactive or misreactive species without performing experiments. [Pg.146]

A disadvantage of this procedure is that it requires long reaction times, and also needs relatively reactive glycosyl acceptors. In such situations, the use of silver triflate as promoter and a glycosyl donor having a benzyl group in the 2-position of the glycosyl donor has been proved to be useful.12,28... [Pg.77]
