Heterocycles. Part XVII. Synthesis of New Substituted 2,3,3a,4,5,6-Hexahydrobenzocycloheptapyrazoles and Related Compounds
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-hexahydrobenzocycloheptapyrazoles III-VI respe

Heterocycles. Part X. Synthesis of New Pyrimidine Systems
Selected aryl aldehydes I were reacted with 1-benzosuberone to give the corresponding 2-arylidene-1-benzosuberone II.Condensation of these chalcones with urea and thiourea revealed the formation of the corresponding substituted pyrimidin-2-ones III, and p
