Abstract

A stereospecific 7-step synthesis of (-)-indolactam V1 from tryptophan methyl ester is described. The key steps are the photocyclisation of the dichloroamide 6 to give the isomeric 7-hydroxy-7-isopropylpyrrolo[4,3,2-fg][3]benzazocines 16 + 18 and the nitrene-mediated ring expansion of the derived azide 5 to give the 9-membered imine 4. The synthesis is completed by stereoselective reduction of the imine bond and N-methylation.
