| Abstract: | The reaction of substituted cinnamonitriles with 5,5-dimethyl-1,3-cyclohexanedione in 95% ethanol catalyzed by KF-montmorillonite, provides a fast, efficient and high-yielding access to 2-amino-3-cyano-4-aryl-7,7-dimethyl-5-oxo-4H-5,6,7,8-tetrahydrobenzob]pyran. The significant effects of the solvent and the dosage of catalyst are also discussed. |
