【 摘 要 】
The aldol condensation of various aromatic aldehydes with cycloalkanones using ethanolic KOH afforded α,ά-bis (substituted-arylidene) cycloalkanones in excellent yields. The cyclization of the resulting cycloalkanones with phenyl hydrazine in the presence of catalytic amounts of DABCO (1,4-diazabicyclo[2.2.2]octane) under solvent-free conditions afforded 7-benzylidene-2,3-diphenyl-3,3a,4,5,6,7-hexahydro-2H-indazole derivatives in good to excellent yields.
