Solid-phase synthesis of pyrrolo[2,1-c][ and ]benzodiazepine-5,11-diones

The solid-phase synthesis of biologically important pyrrolo[2,1-c][1,4]benzodiazepine-5,11-diones using Wang resin through amide formation and reductive cyclization procedures is described. Further, N10-substituents have been introduced in the final products and these have been cleaved from the solid support in good yields.
