✦ Synopsis


A novel series of synthetic glycolipids, i,3-di-O-alkyl-2-O-(/3-glycosyl)glycerols, and their efficient synthetic route were proposed. These glyceroglycolipids were synthesized in good overall yields and stereoselectivity in five steps via trichloroacetimidate glycosylation with 1,3-di-O-alkylglycerols. This route was applied to prepare the glycolipids bearing a cello-or malto-oligosaccharide with a definite number of sugar residues from one to six. Thin-layer chromatography, elemental analysis, nuclear magnetic resonance spectroscopy and infrared absorption spectroscopy confirmed that these glycolipids were chemically pure compounds.
