Abstract
3-Hydroxypyridine N-oxide reacts readily in acetic anhydride with ethyl cyanoacetate, cyanoacetone and malononitrile. The three reaction products (2-substituted-3-acetoxypyridines) show different equilibria between tautomeric structures; in strong acids they undergo cyclization to 3-substituted 2-aminofuro[3,2-b]pyridines.
