A facile and highly stereoselectivesynthesis of 1-thiotrehalose, that is, α,α-S-linked trehalose, is described. Glycosylation of configurationally pure α-glucosyl thiol 5 with glucosyl trichloroacetimidate 6 or glucosyl thioimidate 9 followed by deprotection afforded 1-thiotrehalose in excellent α-stereoselectivity and high yield. A different synthetic route to the key building block, α-glucosyl thiol

We describe here the first synthesis of thioglycoside analogues of maradolipid, based on a new procedure for the synthesis of 1-thiotrehalose developed recently in our laboratories. The challenging alpha,alpha-(1 -> 1') thioglycosidic linkage was constructed by Schmidt's inverse procedure in very high yield and excellent stereoselectivity. Subsequent protecting group manipulation and coupling with different fatty acids led smoothly to a group of symmetrical and unsymmetrical thiomaradolipids which would be of high value for biological studies.
