Acylations of free glycosylamines 1-3 using 3-acyl(or alkoxycarbonyl)-5-methyl-1,3,4-thiadiazole-2(3H)-thiones 5 and 2-acylthio-5-methyl-1,3,4-thiadiazoles 6 as acylating reagents, provided high yields of N-acyl-glycosylamines, whereas reactions with 3-acyl-thiazolidine-2-thiones 4 caused drastic deglycosylations.
