O-BENZYL PROTECTING GROUPS AS HYDROGEN DONORS IN CATALYTIC TRANSFER HYDROGENOLYSIS. SELECTIVE DEBENZYLATION OF 1,6-ANHYDRO HEXOSES.
O-benzyl protecting groups may act as hydrogen donors in heterogenous catalytic transfer hydrogenolysis.Hydrogenolysis of compunds 1 - 4 demonstrated that this hydrogen transfer occurs adjacent cis-disposed hydroxyl groups are present.
