The efficient synthesis of novel azetidin-2-ones 6 has been established. Thus, condensation of 5-[(2-methyl-1H-benzimidazol-1-yl)methyl]-1,3,4-thiadiazol-2-amine 4 with various aromatic aldehydes afforded 5-[(2-methyl-1H-benzimidazol-1-yl)methyl]-N-[(substituted) phenylmethylidene]-1,3,4-thiadiazol-2-amine 5 which on cycloaddition with chloroacetyl chloride in the presence of triethylamine catalyst
已经建立了新型氮杂环丁烷-2-酮6的有效合成。因此,将5-[(2-甲基-1 H-苯并咪唑-1-基)甲基] -1,3,4-噻二唑-2-胺4与各种芳族醛缩合,得到5-[(2-甲基-1 H-苯并咪唑-1-基)甲基] -N -[(取代的)苯基亚甲基] -1,3,4-噻二唑-2-胺5在三乙胺催化剂存在下与氯乙酰氯环加成后生成3-氯-1 -5-[(2-甲基-1 H-苯并咪唑-1-基)甲基] -1,3,4-噻二唑-2-基} -4-(取代的)苯基氮杂环丁烷-2-酮6。合成化合物的结构已根据其元素分析和光谱数据进行了阐明。筛选所有合成的化合物的抗微生物活性。
