Highly α-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 α-selectivity was obtained by the use of this solvent in comparison to conventional diethyl ether. α-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.
