Acylpyruvamides and acylpyruvoylhydrazines

Substituted aroylpyruvamides react with hydrazine and phenylhydrazine to give 5-aryl-5-hydroxy-2-pyrazoline-3-carboxamides rather than 5-arylpyrazole-3-carboxamides as suggested before. The structures of the compounds obtained are discussed. For Part 6, see Ref. 1. Translated fromIzvestiya Akademii Nauk. Seriya Khimicheskaya. No. 7, pp. 1396–1398, July, 1999.     

The reactions of aroylpyruvic acids and their derivatives witho-aminophenyldiphenylmethanol

Aroylpyruvic acids and their methyl esters react witho-aminophenyldiphenylmethanol to form 4-aryl-2-[2-(1-hydroxydiphenylmethyl)phenylamino]-4-oxobut-2-enoic acids and their esters. The α-enamino acids obtained undergo intramolecular heterocyclization in the presence of Ac₂O to affort substituted 4,5-dihydrobenzo[e][1,4]oxazepin-3(1H)-ones. The reaction of 5-arylfuran-2,3-diones witho-aminophenyldiphenylmethanol leads to products of decyclization, 2-(1-hydroxydiphenylmethyl)phenylamides of 4-aryl-2-hydroxy-4-oxobut-2-enoic acid, which upon heating in AcOH or Ac₂O yield 3-aroylacetyl-1,1-diphenyl-1H-benzo[d][1,3]oxazines.
