Herein, we present a copper-catalyzed tandem reaction of 2-aminoimidazolines and ortho-halo(hetero)aryl carboxylic acids that causes the regioselective formation of angularly fused tricyclic 1,2-dihydroimidazo[1,2-a]quinazolin-5(4H)-one derivatives. The reaction involved in the construction of the core six-membered pyrimidone moiety proceeded via regioselective N-arylation–condensation. The presented
在此,我们提出了2-氨基咪唑啉和邻卤(杂)芳基羧酸的铜催化串联反应,该反应导致有角度稠合的三环1,2-二氢咪唑啉[1,2 -a ]喹唑啉-5(4)的区域选择性形成H )-一衍生物。构建核心六元嘧啶酮部分所涉及的反应通过区域选择性N -芳基化-缩合进行。所提出的方案已成功应用于完成 TIC10/ONC201 的全合成,TIC10/ONC201 是一种活性角异构体,充当肿瘤坏死因子 (TNF) 相关凋亡诱导配体 (TRAIL):一种备受追捧的抗癌临床药物。
