Vibrio cholerae O1 LPS terminal mono- and disaccharide elements were synthesized by reduction of the azido group in several 4-amino-4,6-dideoxy- D-mannose mono- and disaccharide derivatives, followed by coupling with 2,4- di-O-acetyl-3-deoxy-L-glycero-tetronic acid in the presence of 2-ethoxy-l- ethoxycarbonyl-1,2-dihydroquinoline. This compound represents a useful model in order to elucidate the size of the epitopes which define Ogawa and Inaba serotypes from Vibrio cholerae O1.
Synthesis and crystal structure of methyl 4,6-dideoxy-4-(3-deoxy-L-glycero-tetronamido)-2-O-methyl-α-D-mannopyranoside, the methyl α-glycoside of the terminal unit, and presumed antigenic determinant, of the O-specific polysaccharide of Vibrio cholerae O:1, serotype Ogawa

Methyl 4-azido-4,6-dideoxy-3-O-benzyl-α-D-mannopyranoside and its analogous 3-O-(4-methoxybenzyl) derivative were methylated and the 2-O-methyl derivatives formed were converted into methyl 4-amino-4,6-dideoxy-2-O-methyl-α-D-mannopyranoside.Reaction of the latter with 3-deoxy-L-glycero-tetronolactone gave the methyl glycoside of 4,6-dideoxy-4-(3-deoxy-L-glycero-tetranamido)-2-O-methyl-α-D-mannopyranose, the monosaccharide that is reported to be the terminal moiety of the O-specific polysaccharide of Vibrio cholerae O:1, serotype Ogawa.The unit cell packing of the compound, which crystallized as a monohydrate, differs from that of the previously described crystalline compound lacking the 2-O-methyl group.The unmethylated sugar is the terminal moiety of the O-specific polysaccharide of Vibrio cholerae O:1; serotype Inaba.The crystal structure of methyl 4,6-dideoxy-2-O-methyl-4-trifluoroacetamido-α-D-mannopyranoside is also described.Keywords: O-Polysaccharide; Vibrio cholerae O:1, serotype Ogawa; α-D-Mannopyranoside, methyl 4,6-dideoxy-4-(3-deoxy-L-glycero-teronamido)-2-O-methyl; Synthesis; Antigenic determinant
