Shanghai Institute of Materia Medica, Chinese Academy of Sciences, Shanghai, 200031

Received Date: 14 April 1995

Palladium acetate catalyzed cyclization of 1-[(6-bromo-1,3-benzodioxol-5-yl)carbonyl] 2,3-dihydro-1H-indole (7a) leading to the anhydrolycorine-7-one (1a) as the key step in a new synthesis of Crinum alkaloids is described.
