A newseries of quinazolinone derivatives were synthesized starting with anthranilic acid and cinnamoylisothiocyanate in high yields 55–99%. Their structures were elucidated by 1H/13C NMR, FTIR spectroscopy, MS and elemental analysis. The study of the biological activity of all the novel compounds is reported. The minimal inhibitory concentration of some quinazolin-5-one derivatives showed potential
从邻氨基苯甲酸和肉桂酰基异硫氰酸酯开始,合成了一系列新的喹唑啉酮衍生物,产率高,可达55-99%。通过1 H / 13 C NMR,FTIR光谱,MS和元素分析阐明了它们的结构。报道了所有新化合物的生物学活性的研究。与参考头孢噻肟相比,某些喹唑啉-5-酮衍生物的最低抑菌浓度显示出对革兰氏(+ ve)和革兰氏(-ve)微生物的潜在活性。此外,与标准药物制霉菌素相比,喹唑啉-5-酮的某些衍生物可被视为抗真菌药。

2-(2-Arylvinyl)-6-methyl-4-mercapto-5-acetylpyrimidine derivatives 3 a − d , were synthesized form the reaction of the appropriate isothiocyanate derivatives 1 with α, β -unsaturated aminoketone 2 . Compound 3 was alkylated with methyl iodide, ethyl chloroacetate and/or bromosugar to afford 6 , 9 , and 22 a − c respectively. Cyanoethylation of 3 b afforded 6 b which upon cyclization with hydrazine
