Stereoselective Synthesis of Long-chain 1-O-(β-D-Maltosyl)-3-O-alkyl-sn-glycerols (Alkyl Glyceryl Ether Lysoglycolipids)
The synthesis of long-chain 2-O-benzyl-3-O-alkyl-sn-glycerols 5 was improved, making these compounds easily accessible for glycosylation experiments.Glycosylation with α-acetobromomaltose following a modified Koenings-Knorr procedure after removal of the protective groups yielded the title compound 9 in good yields.These compounds represent examples of alkyl glyceryl ether lysoglycolipids.Some properties of these amphiphilic compounds with a nonionic carbohydrate head-group differ not much (critical micell concentration, hemolytic activity), other properties differ very much (antitumor efficiency) from the properties of the analogous compounds with a zwitterionic phosphorylcholine head-group.
