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 hydrazine or methylhydrazine to give tricyclic products optionally followed by catalytic dehydrogenation and/or alkylation with a strong base and methyl iodide to give various other compounds within the scope of the invention.
