Palladium-catalysed synthesis of 1-isoindolecarboxylic acid esters and sequential Diels–Alder reactions: access to bridged- and fused-ring heterocycles
Palladium-catalysed synthesis of 1-isoindolecarboxylic acid esters and sequential Diels–Alder reactions: access to bridged- and fused-ring heterocycles
Bicyclopyrroles were efficiently converted to the corresponding isoindoles by a retro Diels-Alder reaction in supercriticalcarbondioxide. By adding ethylene gas as an oxygen scavenger, the isoindole yield was further improved.

Two efficient palladium-catalyzed intramolecular alpha-arylation reactions of alpha-amino acid esters have been developed that allow either 1-isoindolecarboxylic acid esters or the corresponding isoindolines to be selectively synthesized simply by a slight change of reaction conditions.
