aerobic intramolecular dearomative coupling reaction of tethered phenols using a catalytic system consisting of a chromium–salen (Cr–salen) complex combined with a nitroxyl radical. This novel catalytic system enables formation of various spirocyclic dienone products including those unable to be accessed by previously reported methods efficiently under mild reaction conditions.
我们描述了使用由铬-salen(Cr-salen)配合物与硝酰基自由基组成的催化体系,使束缚酚的需氧分子内脱芳香反应。这种新颖的催化系统能够在温和的反应条件下有效地形成各种螺环二烯酮产物,包括那些以前报道的方法无法有效利用的产物。
