stereoselective synthesis of 1,2-cis-glycosyl sulfones and their application to one-pot Julia olefination are reported. Glycosylation of heteroarylthiols using glycosyl iodides as glycosyl donors afforded heteroaryl 1-thioglycosides in a highly 1,2-cis-selective manner. 1,2-cis-Glycosyl sulfones were obtained by oxidation of the resulting 1-thioglycosides by magnesium monoperphthalate.
