A multi-gram epoxidation of 3,4,6-tri-O-benzyl-D-glucal and D-galactal with dimethyldioxirane (DMDO) generated in situ from Oxone/acetone in a biphasic system (CH(2)Cl(2)-aqueous NaHCO(3)) resulted in the formation of the corresponding 1,2-anhydrosugars in a 99% yield and 100% selectivity. In a similar way, 3,4,6-tri-O-acetyl-D-glucal afforded a 7:1 mixture of the corresponding gluco and manno derivatives in an 87% overall yield.
