Tri cyclic hetero aromatic ring systems 3. synthesis of 1h 6h di pyrazolo 3 4 b 3' 4' d pyridin 3 ones


, : Tri cyclic hetero aromatic ring systems 3. synthesis of 1h 6h di pyrazolo 3 4 b 3' 4' d pyridin 3 ones. Monatshefte fuer Chemie 113(1): 123-127

The reaction of hydrazines with substituted ethyl 4-chloro-1H-pyrazolo[3,4-b]pyridine-3-carboxylates led to formation of 1H,6H-dipyrazolo[3,4-b:3',4'-d]pyridin-3-ones. [Implications for use of the synthesized compounds as tranquilizing and antiinflammatory agents are discussed.].

Various quinol-4-yl hydrazones on heating in boiling solvents undergo cyclizations to give 1H-pyrrolo[3,2-c]quinolines in good yields. Some pyrroloquinolines were alkylated to provide their N-alkyl derivatives. [Such tricyclic heteroaromatic ring...
