Auto‐Tandem Catalysis with Ruthenium: From <i>o</i>‐Aminobenzamides and Allylic Alcohols to Quinazolinones <i>via</i> Redox Isomerization/Acceptorless Dehydrogenation

Abstract

Abstract A strategy for the synthesis of quinazolinones via Ru‐catalyzed redox isomerization/acceptorless dehydrogenation was proposed and accomplished. In the presence of a commercially available [( p‐ cymene)Cl 2 ] 2 , a range of desirable products were obtained with o ‐aminobenzamides and allylic alcohols as starting materials in moderate to high yields. This strategy is attractive due to high atom efficiency, and minimal consumption of chemicals and energy. magnified image
