  • New Factors Governing Stereoselectivity in Borohydride Reductions ofβ-D-Glycoside-2-uloses − The Peculiar Effect of “Activated” DMSO

    DOI:10.1002/1099-0690(200012)2000:23<3931::aid-ejoc3931>3.0.co;2-w
    日期:2000.12
    Comparative evaluation of the manno/gluco ratios obtained in the conventional reductions of beta -D-glucoside-2-uloses (1-4, 13 and 14) reveals the influence of the substitution pattern: the presence of a 4,6-O-acetal function results in lower stereoselectivity in the monosaccharide-uloside cases and low stereoselectivity in the disaccharide-uloside cases, while the absence of a 4,6-O-acetal group provides distinctly higher stereoselectivity. The 3-O-benzyl and 3-O-allyl ethers vicinal to the carbonyl to be reduced have a similar influence on the steric outcome of the carbonyl reduction. A peculiar effect of acetoxydimethylsulfonium acetate ("activated" DMSO) was observed. In all cases, its presence strongly increased the manno-selectivity of the reduction. A simple, preparatively expedient, commonly suitable protocol has been elaborated for achieving high manno-selectivities and, hence, satisfactory yields.
