A series of novel4‐(substituted phenyl)‐2‐(thiophen‐2‐yl)‐2,3‐dihydro‐1H‐benzo[b][1,4]diazepine have been synthesized from 3‐(substituted phenyl)‐1‐(thiophen‐2‐yl)prop‐2‐en‐1‐one. 3‐(Substituted phenyl)‐1‐(thiophen‐2‐yl)prop‐2‐en‐1‐one was prepared by condensing 2‐acetyl thiophene with various aromatic aldehydes in the presence of 20% NaOH as base. Different 3‐(substituted phenyl)‐1‐(thiophen‐2‐yl)prop‐2‐en‐1‐one
由3-(取代的苯基)合成了一系列新颖的4-(取代的苯基)-2-(噻吩-2-基)-2,3-二氢-1 H-苯并[b] [1,4]二氮杂-1(噻吩-2-基)prop-2-en-1。3-(取代的苯基)-1-(噻吩-2-基)丙-2-烯-1-酮是通过在20%NaOH为碱的情况下将2-乙酰基噻吩与各种芳香醛缩合而制得的。在NaOH为碱的情况下,用邻苯二胺环化不同的3-(取代的苯基)-1-(噻吩-2-基)丙-2-烯-1-烯-生成4-(取代的苯基)-2- (噻吩-2-基)-2,3-二氢-1 H-苯并[b] [1,4]二氮杂derivatives衍生物。合成化合物的结构通过IR确证,11 H NMR,质谱和元素分析。已对所有化合物的抗微生物,止痛和抗炎活性进行了筛选。

A series of diverse polycyclic heterocycles containing spirooxindole, pyridine/thiophene, and pyrrolidine/pyrrolizidine/pyrrolothiazole rings have been synthesized through the 1,3-dipolarcycloaddition of azomethineylides generated in situ by the condensation of dicarbonyl compounds (isatin or acenaphthenequinone) and secondary amino acids with dipolarophiles. The method is simple and provides diverse
