Abstract
Flash vacuum pyrolysis (FVP) of 4-acetyltetrazolo [1, 5-a] pyridine 5 at 400° C provides 3- methyl isoxazolo [3, 4-b] pyridine 6 whose structure was confirmed by X-ray crystallography. At higher pyrolysis temperatures, the unstable heteroindoxyl 8 was obtained, which exists as the keto form (1, 2-dihydropyrrolo [2, 3-b] pyridin-3-one) 8K in CDCl3 solution and the enol tautomer (3-hydroxypyrrolo [2, 3-b] pyridine) 8E in DMSO. The heteroindoxyl 8 oxidatively ...
