Perbenzyl derivatives of the disaccharides benzyl 6-O-(alpha(and beta)-D-glucopyranosyl)-alpha-D-galactopyranoside and benzyl 6-O-(alpha(and beta)-D-mannopyranosyl)-alpha-D-galactopyranoside were each prepared in a stereoselective manner by acylation, thionation, and reductive desulfurization. The use of 2,4-bis(4-phenoxyphenyl)-1,3,2,4-dithiadiphosphetane 2,4-disulfide (4b) as a mild thionation reagent for esters and lactones is also described.
