Condensation of 4-benzoyl-1,2-phenylenediamine with sodium pyruvate in acetic acid furnished two products which were identified as 6-benzoyl and 7-benzoyl-3-methyl-2(1H)quinoxalinones (1a,b). Fusion of 1a with aromatic aldehydes furnished the styryl derivatives 2a-c. Alkylation of 1a,b with dimethyl sulphate or ethyl chloroacetate produced the N-alkyl derivatives 3a,b and 4a,b. Hydrazinolysis of the ester derivative 4a with hydrazine hydrate afforded the hydrazide derivative 5 which underwent condensation with aldehydes to give the corresponding hydrazone derivatives 6a,b. In addition, chlorination of 1a with thionyl chloride afforded the 2-chloro derivative 7 which was subjected to reaction with sodium azide and n-butylamine to yield the corresponding tetrazolo (8) and n-butylamino (9) derivatives, respectively. The structures of the compounds prepared were confirmed by analytical and spectral data. Also, some of the synthesized compounds were screened for antimicrobial activity.
4-苯甲酰-1,2-苯二胺与丙烯酸钠在醋酸中缩合,生成两种产物,分别被鉴定为6-苯甲酰和7-苯甲酰-3-甲基-2(1H)喹喔啉酮 (1a,b)。将1a与芳香醛熔融反应生成斯替尔衍生物2a-c。用二甲基硫酸酯或氯醋酸乙酯烷基化1a,b,得到N-烷基衍生物3a,b和4a,b。用肼水合物对酯衍生物4a进行肼解反应,生成肼酰衍生物5,该衍生物与醛发生缩合反应,生成相应的肼酮衍生物6a,b。此外,用亚硫酰氯对1a进行氯化反应,得到2-氯衍生物7,该衍生物与叠氮钠和正丁胺反应,分别生成相应的四唑衍生物(8)和正丁胺衍生物(9)。合成化合物的结构通过分析和光谱数据得到了确认。此外,对一些合成化合物进行了抗菌活性筛选。
