A series of novelmethylene-bis-chalcones was prepared by the reaction of 5,5′-methylene-bis-salicylaldehyde with different acetophenones, subsequent treatment of methylene-bis-chalcones with urea/thiourea gave the corresponding methylene-bis-pyrimidinones/methylene-bis-mercaptopyrimidines in good yields. Characterization of the new compounds has been done by means of IR, 1H NMR, MS and elemental analysis
通过5,5'-亚甲基-双-水杨醛与不同的苯乙酮反应制备了一系列新型亚甲基-双-查尔酮,随后用脲/硫脲处理亚甲基-双-查尔酮,得到了相应的亚甲基-双-嘧啶酮/亚甲基双巯基嘧啶,收率高。通过IR,1 H NMR,MS和元素分析对新化合物进行了表征。还已经评估了化合物的抗菌,抗结核和抗真菌活性。
