Several isomeric glycosyl glycerols were synthesized. Acetylated allyl glycosides of D-glucose and D-galactose were transformed into 1-O-(glycopyranosyl)-rac-glycerols in a three step procedure via the corresponding 2,3-epoxypropyl glycosides and the peracetylated glycosyl glycerols. Tetra-O-benzyl-D-glucose was glycosylated with 1,3-di-O-benzylglycerol to give the alpha-anomer preferentially. The 2-O-(tetra-O-acetyl-beta-glycopyranosyl)-sn-glycerols and 2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding alpha-derivatives of D-mannose were synthesized by selective glycosylation methods from 1,3-di-O-benzylglycerol and 1,3-O-benzylideneglycerol, respectively, and activated sugar compounds followed by hydrogenolysis. After long chain acylation and selective deacetylation the 1,3-di-O-acyl-2-O-(beta-glycopyranosyl)-sn-glycerols of D-glucose, D-galactose and N-acetyl-D-glucosamine and the corresponding a-derivative of D-mannose were synthesized.
