| Abstract: | 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  -selective mannosylation of secondary alcohol acceptors was achieved with 2,3,4,6-tetra-O-benzyl-d-mannopyranosyl pentenoate to give -disaccharides in good yields. |
