A method for the catalytic regioselective synthesis of C3-substituted dihydrobenzofurans (DHBs) via [2 + 2] photocycloaddition of alkene and p-benzoquinone is developed. This method realizes the rapid synthesis of DHBs with readily available substrates and simple reaction conditions by using Lewis acid B(C6F5)3 and Lewis base P(o-tol)3 as a catalyst in combination with the classical Paternò–Büchi reaction
开发了一种通过烯烃和对苯醌的[2 + 2]光环加成催化区域选择性合成C 3 -取代的二氢苯并呋喃(DHBs)的方法。该方法以路易斯酸B(C 6 F 5 ) 3和路易斯碱P( o -tol) 3为催化剂,结合经典的Paternò–Büchi反应,实现了底物易得、反应条件简单的DHBs的快速合成。 .
