发展了一种高效的钯(II)催化的苯酚分子间直接邻烯基化和乙酰氧基化反应。反应通过七元环钯中间体进行，表现出完全的区域选择性和非对映选择性。该方法也为香豆素和苯并呋喃的合成提供了一条有效的途径。
An efficient palladium(II)-catalyzed intermolecular direct ortho-alkenylation and acetoxylation of phenols has been developed. The reaction proceeded via a seven-membered cyclopalladated intermediate and showed complete regio- and diastereoselectivity. The approach also provided an efficient route for the synthesis of coumarins and benzofurans.
