A facile ring‐enlargement reaction of 2,6‐diphenyl‐4H‐pyrazolo[5,1‐c][1,4]oxazin‐4‐one is described, generating the pyrazolo[5,1‐d][1,2,5]triazepin‐4‐ones in good yields. Structures of the prepared compounds were determined on the basis of IR, 1H‐ and 13C‐NMR, and HR‐MS data. Moreover, the molecular structure was confirmed by the X‐ray crystal‐structure analysis of one compound that was prone to crystallization
2,6-二苯基-4-的一种简便环放大反应ħ吡唑并[5,1- c ^ ] [1,4]恶嗪-4-酮中描述,产生吡唑并[5,1- d ] [1, 2,5] triazepin-4-ones高产。根据IR,1 H和13 C-NMR和HR-MS数据确定了所制备化合物的结构。此外,通过一种易于结晶的化合物的X射线晶体结构分析证实了其分子结构。初步生物学评估表明,化合物2e - 2h在低浓度时能促进血管内皮细胞的活力并抑制其凋亡。
