1,3-Dipolar cycloaddition of 5-azidomethyl-3-p-substituted phenyl-1,2,4-oxadiazoles to phenyl vinyl sulfone and bismaleimide gives rise straightforwardly to 1-((3-(p-substituted) phenyl-1,2,4-oxadiazol-5-yl)methyl)-4-(phenylsul\-fonyl)-4,5-dihydro-1H-1,2,3-triazoles and bisdihydropyrrolo[3,4-d][1,2,3]triazole-4,6(3aH,5H)-diones. The structures of the new cycloadducts were elucidated by means of IR, NMR (^1H, ^13}C, 2D), mass spectra, and physical characteristics (mp and R_f values). In addition, anticancer activities of the cycloadducts against MCF-7 cells were also investigated.
5-叠氮甲基-3-对取代苯基-1,2,4-嗯二唑与苯基乙烯砜和双马来酰亚胺的1,3-偶极环加成反应,直接生成1-((3-(对取代)苯基-1,2,4-嗯二唑-5-基)甲基)-4-(苯磺酰基)-4,5-二氢-1H-1,2,3-三唑和双二氢吡咯并[3,4-d][1,2,3]三唑-4,6(3aH,5H)-二酮。通过红外、核磁共振(^1H、^13C、2D)、质谱和物理性质(熔点和R_f值)阐明了新环加合物的结构。此外,还研究了这些环加合物对MCF-7细胞的抗癌活性。
