An efficient and BF3·Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation–cyclization between 2-formylarylketones and electron-rich arenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards
已经描述了一种高效率且高产率的,由BF 3 ·Et 2 O催化的化学选择性合成多种1,3-二芳基异苯并呋喃的方法。该反应通过2-甲酰基芳基酮与富电子芳烃/杂芳烃之间的依次加氢芳基化-环化进行。所开发方法的优点包括操作简便,广泛的底物范围以及对克级合成的适用性。异苯并呋喃衍生物作为二烯的用途扩展到了用DMAD合成[4 + 2]环加合物和高产率合成1,2-二羰基芳烃。
