- Synthesis of thioglycoside analogues of maradolipid
-
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 α,α- (1→1′) thioglycosidic linkage was constructed by Sch

- An Expeditious Synthesis of 1-Thiotrehalose
-
A two-step synthesis of 1-thiotrehalose is reported. In the key TMSOTf-mediated double thioglycosylation step, the tri- O -benzyl 1,6-anhydro-D-glucose reactant behaves both as a glycosyl donor and a glycosyl acceptor precursor. In this highly convergent process, two carbon-sulfur bonds are created at the anomeric positions with a high level of stereocontrol.

- A facile and highly stereoselective synthesis of 1-thiotrehalose
-
A facile and highly stereoselective synthesis 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 5, was also investigated in this report.

- Hydrogen fluoride-mediated synthesis of 1-thiotrehaloses involving reaction of D-glucose with hydrogen sulfide
-
Hydrogen sulfide reacted with D-glucosde in hydrogen fluoride solution to yield preponderantly α,α-1-thiotrehalose, β,β-1-thiotrehalose, and the α,β anomer. Conditions were found under which the thiotrehaloses were obtained in the respective proportions of 8:5:5.
