Thiocrown Ether: Reversing SN1 to SN2 Pathways in 1,2-cis Phosphoryl Glycosylation

Thiocrown Ether: Reversing SN1 to SN2 Pathways in 1,2-cis Phosphoryl Glycosylation

Phosphoryl glycosides are a class of complex carbohydrates that are ubiquitous and critically important in biological systems. Given their significant roles in various physiological and pathophysiological processes, the synthesis of phosphoryl glycosides has become a central scientific issue in glycoscience. However, their preparation faces two major challenges: achieving high stereoselectivity in phosphorylated glycosides and maintaining … Read more
