Synthesis of the tetrasaccharide repeating unit of the antigen from Escherichia coli O126 as its methyl glycoside

The tetrasaccharide repeating unit (17) of the antigen from E. coli O126 has been synthesized as its methyl glycoside by sequential addition of monosaccharide derivatives. The formation of the β-mannosidic linkage was achieved by Swern oxidation of the gl

SYNTHETIC STUDIES ON NOGALAMYCIN: STEREOSPECIFIC C-5 ALKYLATION OF A SUGAR DERIVATIVE VIA CLAISEN REARRANGEMENT AND A NEW ROUTE TO 1,1,4-TRIALKOXYBUTA-1,3-DIENES.

Claisen rearrangement of the 4-methoxybutadienylether of the allylic alcohol 13 which was made in 15 steps from D-glucose, afforded one major aldehyde 17 or 18 in good yield.All attempts to oxidize to an acid were unsuccessful.The model compound 24 and compound 13, were converted respectively to the α, β-unsaturated esters 25 and 26.Compound 25 was further transformed into 1,1,4-trialkoxybuta-1,3-diene 27 which was found unreactive towards quinones.
