excellent yields. A one‐pot, unsymmetrical, twofold C−H functionalization involving intramolecular C−C and intermolecular C−C/C−N bond formations is successfully demonstrated by using a single set of catalytic reaction conditions, which is unprecedented thus far. A novel isoquinolone‐bearing dihydrobenzofuran is constructed through an unsymmetrical twofold C−H functionalization.
甲基苯基硫肟亚胺(MPS)用作链烯基苯甲酸衍生物在钌催化的分子内氢芳基化反应中的导向基团,从而以良好或优异的收率提供二氢苯并呋喃和二氢吲哚。通过使用一组催化反应条件成功地证明了涉及分子内C-C和分子间C-C / C-N键形成的单锅,不对称,双重CH功能化,这是迄今为止前所未有的。通过不对称的双重CH官能团构建了一种新型的带有异喹诺酮的二氢苯并呋喃。
