The investigation is related to the development of a general strategy for the synthesis of glycolipids including analogs bearing polyunsaturated fatty acids. In particular, here we report exceptionally mild and selective conditions to remove acetate protecting groups from glyceroglycolipids by hydrazinolysis. Synthetic 1,2-O-di-arachidonoyl-3-O-β-galactosyl-glycerol was used as representative of polyunsaturated...
A new significant structural feature of the more abundant polysaccharide (caryophyllan) of the lipopolysaccharide fraction (LPS) from Pseudomonas caryophylli is reported. In particular, the occurrence in the caryophyllan structure of β-linkages, about 11%, besides the more abundant α-linkages, has been evidenced by spectroscopic investigation of the polymer-degraded compounds.
