The allylation of protected polyhydroxy aldehydes 1 and 14 has been achieved by indium metal with ultrasound promotion generating the diastereomeric pair of homoallylic polyols 3, 4 and 16, 17 respectively with moderate to good stereoselectivity.Pursuing this allylation strategy with the corresponding deprotected polyhydroxy aldehydes led to the same pair of homoallylic polyols but with a quite different ratio of the diastereomers generated.The polyols were further transformed to 2-deoxy (5 and 6) and 2,6-dideoxy (18 and 19) carbohydrates by ozonolysis.
SYNTHESIS OF SOME DEOXY, UNSATURATED, AND DIDEOXY SUGARS VIA REGIOSELECTIVE THIOACYLATION OF GLYCOPYRANOSIDES BY THE DIBUTYLTIN OXIDE METHOD

Treatment of non-protected glycopyranosides (Me α-D-Glc, Me β-D-Glc, Me α-D-Xyl, and Me β-D-Xyl) with dibutyltin oxide followed by thioacylation with phenoxythiocarbonyl chloride gave the mono-thionocarbonates regioselectively in high yields.Acetylation o
