Acetoxylation of N-oxide of furo[2,3-b]- 2a, -[3,2-b]- 2b, -[2,3-c]- 2c and -[3,2-c]pyridine 2d with acetic anhydride afforded compounds substituted normally at the α- or γ-position to the ring nitrogen, 3a, 4a, 4b, 3d, 4d, 8 and 9, and in addition compounds substituted on the furan ring, 5a, 6a, 5b, 6b, 7b, 5c and 7c which were unexpected compounds. The structures of these compounds were established from the ir, nmr and mass spectra, and x-ray crystal analysis of 5b.
