A NOVEL ROUTE TO 1,4-ANHYDRO DERIVATIVES OF β-D-GALACTOPYRANOSE

Treatment of 1-O-acetyl-4-O-mesyl derivatives of α-D-glucopyranose with sodium azide in N,N-dimethylformamide gave 1,4-anhydro derivatives of β-D-galactopyranose and not the expected 4-azides. 1,4-Anhydro-6-azido-2,3-di-O-benzoyl-6-deoxy-β-D-galactopyrano
