Reactions of 2-Mono- and 2,6-Disubstituted 4-Pyrones with Phenylhydrazine as General Method for the Synthesis of 3-(N-Phenylpyrazolyl)Indoles

Phenylhydrazine reacted regioselectively with 6-substituted 4-pyrone-2-carboxylic acids (or esters) in protic and aprotic solvents, leading to phenylhydrazones of 3-(3-R-1-phenylpyrazol-5-yl)- or 3-(5-R-1-phenylpyrazol-3-yl)pyruvic acids (or esters), resp

New derivatives of 6-phenylcomanic acid

Ethyl 6-phenylcomanic acid with hydrazine hydrate and hydroxylamine gives 4-oxo-6-phenyl-4H/-pyran-2-carbohydrazide and 4-oxo-6-phenyl-4H-pyran-2- carbohydroxamic acid, whereas 6-phenylcomanic acid with ammonia in aqueous DMSO gives 4-hydroxy-6-phenylpico
