-2-carboxylate with ammonia. Upon addition of aldehydes or ketones to the reaction mixture, 3-substituted 4-cyano-1,2,3,4-tetrahydro-1-oxo-β-carbolines were obtained in a one-pot condensation. When cyclic ketones are used, the procedure allows a convenient synthesis of tetracyclic spiro compounds. β-carbolines - cyclizations - multicomponent reactions - indoles - lactams
