Convenient Synthesis of Quinolines from α‐2‐Nitroaryl Alcohols and Alcohols via a Ruthenium‐catalyzed Hydrogen Transfer Strategy

Abstract

Abstract A new and straightforward method for convenient synthesis of quinolines via a ruthenium‐catalyzed hydrogen‐transfer strategy has been demonstrated. By employing a commercially available ruthenium catalyst system, different α‐2‐nitroaryl alcohols were efficiently converted in combination with a variety of alcohols into various substituted products in reasonable to good yields upon isolation. The synthetic protocol is operationally simple with a broad substrate scope, and there is no need for the use of specialized reducing agents, making it a practical approach for versatile preparation of various quinoline derivatives.
