A palladium-catalyzed cascade approach for the synthesis of 3,3a,4,6,7,8,9,9a-octahydro-1H-benzo[f]isoindole-1,5(2H)-diones

Abstract

A synthetic method for the preparation of 3,3a,4,6,7,8,9,9a-octahydro-1 H-benzo[ f]isoindole-1,5(2 H)-diones from 1,6-dienes and vinyl iodides is developed using PdCl2(PPh3)2 as the catalyst. The presented approach exhibits a good functional group tolerance and affords moderate yields of the products. A mechanism is also proposed.
