以过渡金属钌(II)为催化剂, 双三氟乙酰氧基碘苯(PIFA)为氧化剂, 通过一步反应在烷氧基芳基醚对位选择性地实现羟基化, 得到了对烷氧基苯酚(p-AOPs)类化合物. 该类化合物去芳构化后, 能方便地转化为醌单缩醛(QMAs), 进一步与β-萘酚缩合可得到一些具有广泛应用前景的多环苯并呋喃化合物, 为合成这类重要化合物提供了一种简洁可靠的途径.

关键词: 过渡金属催化, 区域选择性羟基化, C—H活化, 对烷氧基苯酚

p-Alkoxy phenol (p-AOPs) compounds were obtained by one-step selective hydroxylation of alkoxyl-aryl ethers with the transition metal ruthenium(II) as catalyst and [bis(trifluoroacetoxy)iodo]benzene (PIFA) as oxidant. These p-AOPs could be easily converted to quinone monoacetals (QMAs) after dearomatization. Condensation of the QMAs with β-naphthols provided polycyclic benzofurans which have a wide application prospect. The protocol established in this paper offered a facile and reliable way for the synthesis of these important compounds.

Key words: transition metal catalysis, regioselectivity hydroxylation, C—H activation, p-alkoxy phenol
