in a two step procedure, to afford compound ; (c) a 2,4-dichlorophenyl protected phosphatidic acid derivative . Compound could be selectively coupled to the primary hydroxyl function of to afford the fully protected glycophospholipid . Finally, removal of the 2,4-dichlorophenyl and TIPS protecting groups from was performed with syn-4-nitrobenzaldoximate and fluoride ions, respectively, to afford glycophospholipid

A highly efficient one-pot methodology is described for the synthesis of heparin and heparan sulfate oligosaccharides utilizing thioglycosides with well-defined reactivity as building blocks. L-Idopyranosyl and D-glucopyranosyl thioglycosides 5 and 10 were used as donors due to low reactivity of uronic acids as the glycosyl donors in the one-potsynthesis. The formation of uronic acids by a selective
examined for antimicrobial activity against Gram positive, Gram negative bacteria and fungi. The study of their in vitro antimicrobial activity confirms the significant activity of some monogalactosyl diacylglycerol analogues and establishes for the galactose series that the 1,2-disubstitution and the octanoyl chain are the proper structural features for the maximum activity.
