A novel method for the regioselective synthesis of 4-arylpyrimido[1,2-b]indazoles has been developed via the dual C(sp3)–H bond functionalization and C–N bond cleavage of triethylamine. The elusive acyclic enamine intermediates are effectively in situ generated and captured by aromatic aldehydes to form a wide array of tricyclic products from 3-aminoindazoles under the NH4I-mediated aerobic oxidative
通过三乙胺的双C(sp 3)-H键官能化和C-N键裂解,开发了一种新的区域选择性合成4-芳基嘧啶[1,2- b ]吲唑的新方法。难以捉摸的无环烯胺中间体可在NH 4 I介导的需氧氧化条件下有效地原位生成并被芳族醛捕获,从而形成多种由3-氨基吲唑形成的三环产物。该反应具有容易获得的原料,绿色和经济条件以及有价值的产品的特点。
