3-Carbamoyl-6-methyl-5-phenylcarbamoyl-2-thioxo-1,2,3,4-tetrahydropyridine-4-spirocyclohexane has been synthesized by the condensation of cyclohexylidenecyanothioacetamide with acetoacetanilide and piperidine. The structure of the product was established by X-ray structural analysis. 相似文献

Self-condensation of cyclohexylidenecyanothioacetamide gave 2,3-dihydro-5,6-tetramethylenespiro(cyclohexane-2-thieno[2,3-d]pyrimidine)-4(1H)-thione, the structure of which was proved by X-ray analysis. A mechanism is proposed for its formation and its alkylation has been studied. 相似文献
