6]pyrido[2,3-d]pryimidines (10-13) were synthesized via cyclocondensation reactions involving chlorovinyl aldehyde 1 or ketoaldehyde 3 and appropriately substituted 6-aminopyrimidines. The regiochemistry of the compounds was established by 1H NMR and 13C NMR spectral data as well as X-ray crystal data. Compounds 10 and 11 and previously reported homologues 14 and 15 were screened for antimicrobial activity
通过涉及氯乙烯醛1或酮醛3和适当取代的6-氨基嘧啶的环缩合反应,合成了四个新的6H-茚并[2',1':5,6]吡啶[2,3-d]嘧啶(10-13)。化合物的区域化学由1 H NMR和13 C NMR光谱数据以及X射线晶体数据确定。筛选化合物10和11以及先前报道的同系物14和15的抗微生物活性。对于其中一些化合物,观察到中等的抗菌活性。化合物14对金黄色葡萄球菌特别有效。13(C14H7N3Cl2)的晶体数据如下:单斜晶空间群,P21 / n;晶胞尺寸,a = 7.284(1)A,b = 12.800(1)A,c = 13.108(1)A,beta = 93.98(1)度,V = 1219.2(2)A3,Z = 4。
