Notes:
Treatment of 3-O-benzyl-1, 2-O-isopropylidene-3-O-methyl-α-D-xylo-pentodialdlo-1,4-furanose and 2,5-anhydro-3,4-O-isopropylidene-aldehydo-D-ribose with moderately stable and stable phosphonium ylides led to the corresponding terminal-unsaturated sugars obtained as a mixture of cis and trans isomers. The cis:trans ratios were determined by 1H-NMR. and (or) GLC. They showed that steric factors play an important role in the control of the stereochemistry of these reactions.
