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