Glycosyl Disulfides: Novel Glycosylating Reagents with Flexible Aglycon Alteration
摘要:
Glycosyl disulfides have been shown for the first time to be effective glycosyl donors. Glucosylation and galactosylation of a panel of representative alcohol acceptors allowed the formation of 28simple glycosides, disaccharides, and glycoamino acids in yields of up to 90%. As well as providing a novel class of effective glycosyl donors, the ability to easily alter the nature of the aglycon and the ability to differently activate donors that differ only in their aglycon simply through altering conditions lends glycosyl disulfide donors to their use in latent-active reactivity tuning Strategies,.

Mixed glycosyl disulfides are not only glycomimetics but also glycosyldonors that may be readily constructed in either armed ether-protected or disarmed ester-protected and in soluble or solid-supported forms from corresponding glycosyl methanethiosulfonates and used in the glycosylation of a variety of representative acceptors.
