SYNTHESIS OF ANGULAR BENZODIPYRAZOLES AND RELATED SYSTEMS

A series of benzodipyrazoles was prepared from cyclohexane-1,3-dione.Several related systems with different central rings were also prepared.In addition, benzodipyrazoles were synthesized from 1,4-cyclohexanedione monoethylene

Dipyrazoles and their use as bronchodilators

A group of variously methyl-substituted[1,2-c:3,4-c']dipyrazoles, cyclohepta[1,2-c:3,4-c']dipyrazoles, and cyclopenta[1,2-c:3,4-c']dipyrazoles useful as bronchodilators are described herein. The compounds are prepared by reacting a 1,3-diketone with hydra
