MeOTf- and TBD-Mediated Carbonylation of <i>ortho</i>-Arylanilines with CO₂ Leading to Phenanthridinones

Abstract

Carbonylation of o-arylanilines utilizing CO2 as a carbonyl source for the synthesis of important phenanthridinones with a free (NH)-lactam motif has been described under metal-free condition. A range of o-arylanilines were transformed to the corresponding phenanthridinones in high yields.
