Regioselective acylation of non protected glycopyranosides was performed using 3- acylthiazolidine-2-thiones 1 and the novel 3-acyl-5-methyl-1,3,4-thiadiazole-2(3H)-thiones 2 as the acylating reagents, yielding 6-O-acylated derivatives in high yields. Acylation of free α-D-glucose and α-D-galactose using the same conditions lead to the 6-O-acylglycoses. This reaction is compared with our previous synthesis

laurates of trans‐ol glycosides are effective inhibitors against S. Aureus, while some laurates and myristates of cis‐ol glycosides are moderate inhibitors against both S. Aureus and S. Agona. Studies on antimicrobial structure‐activity relationship of sugar fattyacidesters showed that both the carbohydrate moiety and the length of fattyacid played a vital role on the antibacterial effect.
