  N-cyclohexyl-2-cyanoacetamide was reacted with phenyl isothiocyanates and sulfur to give thiazolidine and bisthiazolidine derivatives. Treatment of N-cyclohexyl-2-cyanoacetamide with phenyl isothiocyanate and KOH followed by in situ heterocyclisation with α-halo compounds gave thiazole derivatives. Treatment of N-cyclohexyl-2-cyanoacetamides with cinnamonitriles gave pyridone and bispyridone derivatives. N-cyclohexyl-2-cyanoacetamide coupled smoothly with benzene-diazonium chloride in pyridine. Cyclocondensation of N-cyclohexyl-2-cyanoacetamide with acetylacetone gave 1,1′-(ethane-1,2-diyl)bis(4,6-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile). Ternary condensation of N-cyclohexyl-2-cyanoacetamide, malononitrile and acetaldehyde gave a bispyridone derivative. Some of the new compounds were tested against bacteria and some fungi.

  N-cyclohexyl-2-cyanoacetamide 与苯基异硫氰酸酯和硫反应生成噻唑烷和双噻唑烷衍生物。用异硫氰酸苯酯和 KOH 处理 N-环己基-2-氰基乙酰胺，然后与 α-卤化合物原位杂环化，得到噻唑衍生物。将 N-环己基-2-氰基乙酰胺与肉桂三酸酯处理，可得到吡啶酮和双吡啶酮衍生物。N-环己基-2-氰基乙酰胺与苯偶氮氯化物在吡啶中顺利结合。N-环己基-2-氰基乙酰胺与乙酰丙酮环缩合生成 1,1′-（乙烷-1,2-二基）双（4,6-二甲基-2-氧代-1,2-二氢吡啶-3-甲腈）。N- 环己基-2-氰乙酰胺、丙二腈和乙醛的三元缩合生成了双吡啶酮衍生物。对其中一些新化合物进行了抗菌和抗真菌测试。
