the central nervous system, anticonvulsant activity, and carcinoma inhibitory activity. Various methods have been employed in literature for the synthesis of substituted 1,2,4,5tetraazepin derivatives (a) Reaction of vitamin Κ and pyruvic acid with thiocarbazide (H2N-NH-CS-NH-NH2) gave 1,2,4,5-tetrazepin-6-ones. (b) Reaction of a-(l-phenyl hydrazino)alkanone phenyl hydrazones with acylating and sulphonating
在甲醇、乙酸混合物 (1:1) 的存在下,取代的 α-乙酰氨基/苯甲酰氨基肉桂酰肼 [2(ag)] 与异硫氰酸甲酯 (MITC) 的环加成产生 1-N-(乙酰基/苯甲酰基)-7-(取代phenylmethylene)-2-methyl-6-oxo-3-thioxo1,2,4,5-tetraazaperhydroepins [3(ag)] 的产率很好。引言 1,2,4,5-tetrazepin 核是一种非常重要的杂环系统,对中枢神经系统具有药物活性、抗惊厥活性和癌抑制活性。文献中已采用各种方法合成取代的 1,2,4,5 四氮杂衍生物 (a) 维生素 Κ 和丙酮酸与硫脲 (H2N-NH-CS-NH-NH2) 反应得到 1,2,4, 5-tetrazepin-6-ones。(b) a-(l-苯基肼基)烷酮苯基腙与酰化和磺化试剂的反应主要攻击肼官能团的伯氨基与羰基二咪唑将其转化为l(H)-l,2,4
