Transmonocyanoacetylation of phenylenediamines: a simple and efficient synthesis of novel N-(aminophenyl)-2-cyanoacetamides and their derivatives
摘要:
Herein, we report a simple and efficient method for the transmonocyanoacetylation of phenylenediamines using inexpensive, commercially available 1-cyanoacetyl-3,5-dimethylpyrazole as a cyanoacetylating agent. This method provides operationally simple and efficient access to N-(aminophenyl)-2-cyanoacetamides under mild conditions with short reaction times. Also, a series of novel N-(functionalized phenyl)-2-cyanoacetamide derivatives have been synthesized through the reaction of N-(4-aminophenyl)-2-cyanoacetamide with various electrophiles, such as carbonyl, acyl chloride, and isothiocyanate derivatives. In all cases, good yields of products were obtained and reaction times were significantly reduced compared with similar reactions. (C) 2015 Elsevier Ltd. All rights reserved.

substitution reaction. The structure of quinoxaline derivatives was confirmed by IR, 1H NMR, and 13C NMR spectra. The antimicrobialactivity of quinoxaline derivatives 4–10 varied from good to potency against the tested strains. The quinoxaline derivatives 4, 6, and 7 exhibited excellent activity, especially against B. pumilis and E. cloacae, with MIC values of (7.8, 15.6, and 3.91 µg/mL) and (15.6, 7.8, and
在全球范围内,由于抗生素耐药性已达到高水平,传染病变得越来越难治疗。此外,有必要开发新的治疗方案来对抗临床环境中日益增长的抗菌素耐药性。通过亲核取代反应合成了新的 3-(pyrrolidin-1-yl)quinoxaline 衍生物4-10通过醚或胺键与 C2 上的不同取代基共轭。喹喔啉衍生物的结构通过 IR、1 H NMR 和13 C NMR 光谱证实。喹喔啉衍生物4-10对测试菌株的抗菌活性从良好到有效不等。喹喔啉衍生物4、6和7表现出优异的活性,尤其是对短小芽孢杆菌和阴沟肠杆菌,与环丙沙星相比,MIC 值为(7.8、15.6 和 3.91 µg/mL)和(15.6、7.8 和 15.6 µg/mL) (7.8 和 15.6 µg/mL)。此外,在 C2 处具有不同甲亚胺部分的杂合喹喔啉显示出中等至良好的抗菌活性,但甲亚胺9和10对大肠杆菌和粪链球菌的 MIC 值分别与环丙沙星 15.6
