Barbiturates 3 as possible antimicrobial agents were obtained by reacting the N,N′‐disubstituted urea 1a or the thiourea analogues 1b,c with the magic malonates 2a,b. On the other hand, reaction of 1a with ethoxycarbonyl isocyanate (4) yielded the substituted s‐triazine‐2,4,6(1H,3H,5H)‐trione 5. The reaction of 4 with 2‐aminomethyl‐benzimidazole (6) gave the allophanate 7 which upon treatment with
通过将 N,N'-二取代尿素 1a 或硫脲类似物 1b,c 与神奇的丙二酸酯 2a,b 反应,获得了巴比妥酸盐 3 作为可能的抗菌剂。另一方面,1a 与乙氧基羰基异氰酸酯 (4) 反应生成取代的 s-triazine-2,4,6(1H,3H,5H)-trione 5。 4 与 2-氨基甲基-苯并咪唑 (6) 的反应得到脲基甲酸酯 7,用 Na2CO3 处理后生成 N-(1H-苯并咪唑-2-基)脲 8。
