lyxose-derived methyl and phenyl ketofuranoses with triethylsilane as nucleophile was found to proceed with good to excellent stereoselectivity to provide the 1,2-cis addition products. The methyl ketoses reacted in a more stereoselective manner than their phenyl counterparts. The stereochemical outcome of the reactions parallels the relative stability of the oxocarbenium ion conformers involved, as
