The PhSeOTf promoted glycosylations of various glycosyl acceptors with mannosyl pentenoates and glucosyl pentenoates as glycosyl donors afforded corresponding disaccharides in high yields. And the present glycosyl pentenoates/PhSeOTf method showed that the complete α-selective mannosylation of secondary alcohol acceptors was achieved with 2,3,4,6-tetra-O-benzyl-d-mannopyranosyl pentenoate to give α-disaccharides
PhSeOTf以甘露糖基戊烯酸酯和葡糖基戊烯酸酯促进各种糖基受体的糖基化,因为糖基供体以高收率提供了相应的二糖。目前的糖基戊烯酸酯/ PhSeOTf方法表明,用2,3,4,6-四-O-苄基-d-甘露吡喃糖基戊烯酸酯可以实现仲醇受体的完整α-选择性甘露糖基化反应,从而获得高收率的α-二糖。
