We report a switchable synthesis of acylindoles and quinoline derivatives via gold‐catalyzed annulations of anthranils and ynamides. α‐Imino gold carbenes, generated in situ from anthranils and an N,O‐coordinated gold(III) catalyst, undergo electrophilic attack to the aryl π‐bond, followed by unexpected and highly selective 1,4‐ or 1,3‐acyl migrations to form 6‐acylindoles or 5‐acylindoles. With the...
Wir beschreiben einen neuen, kurzen und flexiblen Weg zu verschiedenen N‐haltigen polycyclischen aromatischen Kohlenwasserstoffen (PAK) über eine goldkatalysierte π‐Erweiterungsreaktion von Anthranilen mit o‐Ethinylbiarylen als Reagenzien. Diese Strategie nutzt leicht zugängliche Edukte, ist aufgrund einer hohen Stufen‐ und Atomökonomie einfach und zeigt eine gute Toleranz gegenüber funktionellen...
