✦ Synopsis

The keto and gem-ester functionalities of cyclohexanonedicarboxylates (1) offer a facile route for the synthesis of 5,7-diarylspiro [4,5,6,7-tetrahydrobenzo[d][1,2,3]selena/thiadiazole-6,5Ј-(hexahydropyrimidine)]-2Ј,4Ј,6Ј-triones (6 and 8) and -2Ј-thioxo-4Ј,6Ј-diones (7 and 9). The new compounds were characterized by IR, NMR, and CMR spectral data.
