    The synthesis of D-and L-glycero-alpha-manno-thioheptopyranosides, protected with 4,6-O-alkylidenetype acetals is described. In glycosylations carried out with preactivation with the 1-benzenesulfinylpiperidine/trifluoromethanesulfonic anhydride couple, both the D-and L-glycero series exhibit excellent, beta-selectivity with a range of glycosyl acceptors. In contrast, a 4,7-O-alkylidene acetal was found not to afford, beta-selectivity. With a 4,6-O-[1-cyano-2-(2-iodophenyl) ethylidene] acetal protected thioglycoside, excellent, beta-selectivity was obtained in glycosylation reactions, and subsequent treatment with tributyltin hydride and azoisobutyronitrile brought about clean fragmentation to the 6-deoxy-glycero-beta-D-manno-heptopyranosides. This chemistry was applied to the stereocontrolled synthesis of methyl alpha-L-rhamno-pyranosyl-(1 -> 3)-D-glycero-beta- D-manno-heptopyranosyl-(1 -> 3)-6-deoxy-glycero-beta-D-manno-heptopyranosyl-(1 -> 4)-alpha-L-rhamno-pyranoside, a component of the lipopolysaccharide from Plesimonas shigelloides.

    [reaction: see text] A method for the direct stereocontrolled synthesis of D- and L-glycero-beta-D-manno-heptopyranosides such as those found in the repeating unit of the O-specific polysaccharide from the CNCTC 113/92 LPS (serotype 54) is described. The method relies on the presence of a 4,6-O-benzylidene acetal to effect stereocontrol at the anomeric center; the configuration at C6 (L- or D-glycero)
    [反应:请参阅文字]一种直接立体控制合成D-和L-甘油-β-D-甘露聚糖-七吡喃糖苷的方法,例如从CNCTC 113/92 LPS(在O-特异性多糖的重复单元中发现的那些)(描述了血清型54)。该方法依赖于4,6-O-亚苄基乙缩醛的存在,以在异头中心进行立体控制。C6的构型(L或D甘油)的重要性最低。
