- Abstract
A simple and efficient synthesis of E-9-aryl-5-arylidene-1-oxo-1,2,3,4,5,6,7,8-octahydroxanthenes and their lower analogues has been developed by amberlyst-15 catalysed cyclocondensation of E, E- α, α′-diarylidenecyclohexanones and E, E- α, α′-diarylidenecyclopentanones, respectively, with cyclohexan-1,3-diones. The products were obtained in moderate to good yield and their structures were confirmed from analytical and spectral data. [Figure not available: see fulltext.]
