Aryl aldehydes I reacted with 1‐benzosuberone to yield the corresponding 2‐arylidene‐1‐benzosuberones II . Condensation of II with hydrazine and its derivatives provided the substituted 2,3,3a,4,5,6‐hexahydro‐benzo[6,7]cyclohepta[1,2‐ c ]pyrazoles III‐VI respectively. The structures of all products were assigned by chemical and spectroscopic methods.
