  Stereoselective glycosylation using the long-range effect of a [2-(4-phenylbenzyl)oxycarbonyl]benzoyl group

  摘要：

  Highly alpha-selective glucosylation was effected by virtue of the solvent effect of cyclopentyl methyl ether and the long-range assistance of bulky 6-O-protective groups. Higher alpha-selectivity was obtained by the use of this solvent in comparison to conventional diethyl ether. alpha-Selectivity was further improved with the influence of 6-O-substituents, such as TBDPS and phthaloyl groups, the latter being mono esterified with a bulky alcohol.
