pharmaceutically important compounds; however, the efficient synthetic routes are scarce in the literature. We report herein a convenient and efficient route to synthesize these molecules through indium-catalyzed transannulation of pyridotriazoles with arenes. A library of compounds have been synthesized employing the method developed with various substituted pyrido[1,2-a]indole derivatives in moderate
吡啶并[1,2- a ]吲哚是药用和药学上重要的化合物;已知的是吡咯并[1,2- a ]吲哚。然而,有效的合成途径在文献中很少。我们在本文中报道了一种方便有效的途径,通过吡啶催化的吡啶三唑与芳烃的铟催化转环合成这些分子。已经使用中等取代率和良好产率使用各种取代的吡啶并[1,2- a ]吲哚衍生物开发的方法合成了化合物库。使用SMD DCB -M06 / 6-31 ++ G(d,p)/ LANL2DZ // B3LYP / 6-31G(d)/ LANL2DZ方法进行的密度泛函理论研究表明,反应是通过铟-类胡萝卜素络合物进行的。
