Abstract

A one-pot method for joining three separate components leading to an assortment of 4-arylquinazolines (27 examples) in good to excellent yields is described. The method consists of a palladium(II)-catalyzed­ cascade reaction involving C(sp)–C(sp2) coupling followed by intramolecular C–N bond formation. The reaction was readily scaled up to gram quantity and successfully applied to the synthesis of a translocator­ protein (TSPO) ligand.

钯(II)催化的4-芳基喹唑啉一罐组装的三组分串联环化反应


摘要

描述了一种通过一锅法将三个独立的组分连接在一起,从而以良好至极好的收率得到各种4-芳基喹唑啉(27个实例)的方法。该方法由钯(II)催化的级联反应,涉及C(sp)–C(sp 2)偶联,然后形成分子内C–N键。该反应易于按比例放大至克量,并成功地用于合成易位蛋白(TSPO)配体。
