Synthesis of Diverse 4‐Pyrrolin‐2‐ones by Electrochemically Induced Dehydrogenative Regioselective Cyclization of 3‐Aza‐1,5‐dienes and 1,3‐Dicarbonyl Compounds

European Journal of Organic Chemistry, Journal Year: 2024, Volume and Issue: 27(11)

Published: Jan. 20, 2024

Abstract A practical and mild electrochemical dehydrogenative regioselective cyclization method has been established for the synthesis of 4‐pyrrolin‐2‐ones using 3‐aza‐1,5‐dienes 1,3‐dicarbonyl compounds as substrates. This protocol is catalyst‐free, metal‐free, does not require oxidizing agents. It exhibits wide substrate compatibility can be easily scaled up to gram scale.
