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

α-2-Deoxyglycosides were synthesized in ionic liquid ([bmim]BF 4 )by stereoselective glycosylation of endo -glycals with various o -nucleophiles in the presence of catalytic amount of pTSAin 71–95 % yield. High yields, easy recovery of the products, and reusable reaction medium (pTSA/IL couple) with...

Summary:α-2-Deoxyglycosides were synthesized in ionic liquid ([bmim]BF 4 )by stereoselective glycosylation of endo -glycals with various o -nucleophiles in the presence of catalytic amount of pTSAin 71–95 % yield. High yields, easy recovery of the products, and reusable reaction medium (pTSA/IL couple) with consistent activity makes this protocol efficient and environmentally benign.
