3-ARYL- AND 2,3-DIARYL-4-OXO-4,5,6,7-TETRAHYDROINDAZOLES. 1. REACTIONS OF PHENYL- AND TOSYLHYDRAZONES OF DIMEDONE AND CYCLOHEXANE-1,3-DIONE WITH SUBSTITUTED BENZALDEHYDES

Abstract

Sixteen 3-aryl-4-oxo-2-phenyl-4,5,6,7-tetrahydroindazoles were obtained from the reaction of the phenylhydrazones of dimedone and cyclohexane-1,3-dione with 3-bromo-, 4-bromo-, 4-chloro-, 4-fluoro-, 2-hydroxy-, 4-hydroxy-, 4-methoxy-, 2-nitro-, 3-nitro-, 4-nitro-, and 4-dimethylamino-benzaldehydes. The interaction of the tosylhydrazones of dimedone and cyclohexane-1,3-dione with the substituted benzaldehydes gave thirteen 3-aryl-4-oxo-4,5,6,7-tetrahydroindazoles.
