A palladium-catalyzed synthesis of isatins (1H-Indole-2,3-diones) from 1-(2-haloethynyl)-2-nitrobenzenes

Add time:08/22/2019    Source:sciencedirect.com

An inherently regiospecific synthesis of isatins (1H-indole-2,3-diones) starting from 1-halo-2-nitrobenzenes is described. The isatins are formed by an intramolecular palladium-catalyzed annulation of 2-(2-haloethynyl)-1-nitrobenzenes via the formation of 2-haloisatogens.
