本文报道了一种新的、简便的邻羟基二苯乙烯类化合物在高价碘试剂作用下的无金属环化反应，得到2-芳基苯并呋喃和2-芳基萘并呋喃。使用化学计量的（二乙酰氧基碘）苯在乙腈中以良好至优异的产率分离环化产物。
A new and convenient metal-free cyclization of ortho-hydroxystilbenes into 2-arylbenzofurans and 2-arylnaphthofurans mediated by hypervalent iodine reagents is described. The cyclization products are isolated in good to excellent yields using stoichiometric (diacetoxyiodo)benzene in acetonitrile.
