pTSA/[bmim][BF4] Ionic Liquid: A Powerful Recyclable Catalytic System for the Synthesis of α-2-Deoxyglycosides

Methods for 2-Deoxyglycoside Synthesis

Deoxy-sugars often play a critical role in modulating the potency of many bioactive natural products. Accordingly, there has been sustained interest in methods for their synthesis over the past several decades. The focus of much of this work has been on developing new glycosylation reactions that permit the mild and selective construction of deoxyglycosides. This Review covers classical approaches to deoxyglycoside synthesis, as well as more recently developed chemistry that aims to control the selectivity of the reaction through rational design of the promoter. Where relevant, the application of this chemistry to natural product synthesis will also be described.

Facile O-glycosylation of glycals using Glu-Fe3O4-SO3H, a magnetic solid acid catalyst

A new glucose derived magnetic solid acid catalyst (Glu-Fe₃O₄-SO₃H) was synthesized in a convenient and ecofriendly manner and well characterized using FTIR, PXRD, EDAX, SEM, and XPS which showed the presence of Fe₃O₄ embedded on the surface of the catalyst along with –SO₃H, –OH and –COOH functional groups.
