HYDROGENOLYSIS OF THE ISOMERIC 1,2:4,6-DI-O-BENZYLIDENE-α-D-GLUCOPYRANOSE DERIVATIVES WITH THE LiAlH4-AlCl3 REAGENT

Article abstract of DOI:10.1016/0008-6215(83)88111-7

Both isomers of 1,2:4,6-di-O-benzylidene-α-D-glucopyranose (and their 3-O-acetyl and 3-O-benzyl derivatives) have been prepared and their 1H- and C13-n.m.r.spectra assigned.The mode of hydrogenolysis of the dioxolane ring in these isomers by the LiAlH4-Al
