Synthesis and Debenzoylation Products of Two Perbenzoylated 2-Substituted 5-D-Galactosyl- 1,3,4-oxadiazoles

The synthesis of 2-(p-chlorophenyl)-5-[1′2′3′4′5′-penta-O-benzoyl- D-galactopentitol-1-yl]-1,3,4-oxadiazole is described. Its debenzoylation gave an equilibrium mixture of the 1,3,4-oxadiazole derivative without protection of the hydroxyl group and the N-benzoyl-D-galactono-1,4-lactonehydrazone. A s...
