Dehydrative Glycosylation Mediated by 2‐Aryl‐1,3‐dithiane 1‐Oxide via Sequential Activation of Sulfoxide and Sulfide

An experimental and theoretical study on stereocontrolled glycosylations by a “one-pot” procedure

Herein we describe a “one-pot” strategy to install the stereoselectivity of both α- and β-glycosides by changing reaction conditions.

Total synthesis of tricolorin A via interrupted Pummerer reaction-mediated glycosylation and one-pot relay glycosylation

Tricolorin A, a bioactive resin glycoside, was synthesized stepwise or in one pot based on interrupted Pummerer reaction-mediated (IPRm) glycosylation. The stepwise synthesis adopted a [2 + 2] assembly sequence, and all of the glycosidic bonds were constructed efficiently by IPRm glycosylation. The one-pot synthesis employed our recently developed one-pot relay glycosylation strategy, in which two different glycosidic bonds were sequentially connected with only one equivalent of external activator.

Sequential activation of thioglycosides enables one-pot glycosylation

This review describes recent developments in relative reactivity value (RRV) controlled sequential glycosylation, pre-activation based iterative glycosylation, and sulfoxide activation initiated one-pot glycosylation.
