Abstract
We report the de novo asymmetric synthesis of the 3,6-dideoxy sugars abequose, paratose, and tyvelose from 2-acetylfuran. Conversion of this readily available ketone to a pyranone derivative was followed by transformation to either an α- or β-glycoside via diasteroselective acylation. Michael addition at C2 controlled primarily by the C1 configuration in the glycoside produced 3,6-dideoxy-4-keto sugars, which could be reduced and converted to either fully deprotected monosaccharides or to immediate precursors of glycosyl donors.

Abstract
A versatile synthesis of modular ascarosides, a family of signaling molecules from Caenorhabditis elegans and other nematodes, via hydrogenolysis of a cyclic sulfate derived from methyl-α-l-rhamnopyranoside is reported. The route enables selective introduction of different side chains at the 1, 2, and 4 positions of the sugar, as demonstrated for ascarosides from C. elegans and Pristionchus pacificus. Bioassays with synthetic samples of 4'-tigloyl ascaroside mbas#3 revealed its role as an avoidance or dispersal signal.

Abstract
The syntheses of the two colitose-containing trisaccharides 8-methoxycarbonyloctyl (3,6-dideoxy-alpha-L-xylo-hexopyranosyl)-(1-->2)-beta-D-galactopyranosyl -(1-->3)-2-acetamido-2-deoxy-beta-D-glucopyranoside and 8-methoxycarbonyloctyl beta-D-galactopyranosyl-(1-->3)-[(3,6- dideoxy-alpha-L-xylo-hexopyranosyl)-(1-->4)]-2-acetamido-2-deoxy-beta-D- glucopyranoside, and tetrasaccharide 8-methoxycarbonyloctyl (3,6-dideoxy-alpha-L-xylo-hexopyranosyl)-(1-->2)-beta-D-galactopyranosyl - (1-->3)-[(3,6-dideoxy-alpha-L-xylo-hexopyranosyl)-(1-->4)]-2-acetamido-2 -deoxy- beta-D-glucopyranoside are described. The oligosaccharides correspond to structures found in the capsular polysaccharide and the lipopolysaccharide of Vibrio cholerae O139 and also to lipopolysaccharide structures of E. coli O55 and Salmonella greenside. The colitose residues were introduced via dimethyl(methylthio)sulfonium trifluoromethanesulfonate promoted glycosylations using colitose thioglycosides as glycosyl donors.
