NOUVELLE VOIE DE SYNTHESE D'ARYLPYRAZOLO - - QUINOLEINES VIA LA CYCLOADDITION DIPOLAIRE -1,3

The regiospecificity of the diarylnitrilimines (D.A.N.I) action on the heterocycles such as the benzofuranne and N-methylindole has been demonstrated spectroscopically and chemically.With the N-alkylindoles having an alkoxycarbonyle function in the positi

Friedlaender Condensation of 1H-Pyrazolin-5-ones with o-Aminobenzaldehydes. Synthesis of 1H-Pyrazoloquinolines

All the possible 1- and 3-monomethyl, monophenyl, dimethyl, diphenyl, and methylphenyl-1H-pyrazolin-5-ones have been condensed with o-aminobenzaldehyde.In some cases (but not all) 1-H-pyrazoloquinolines (10) are formed together with a variety of other products.The balance between formation of hydrazone 11 and the ring-closed 10 is discussed, as is the formation of other products obtained in these condensations.
