Mn‐Catalyzed Electrochemical Synthesis of Quinazolinones from Primary Alcohols/Benzyl Ethers and o‐Aminobenzamides

An efficient approach for the synthesis of quinazolinones from o ‐aminobenzamides and alcohols by the combination of electrochemistry and redox‐metal catalysis has been developed. Taking manganese(II) sulfate as a redox catalyst, this transformation proceeded smoothly under ambient conditions in an undivided cell to afford quinazolinones in moderate to excellent yields with a wide substrate scope. Benzyl ethers were also suitable participants in the cascade cyclization sequence.
