In a project aimed at the synthesis of analogues of the cytotoxic -carboline alkaloid bauerine C with more advantageous solubility properties, a 3-amino analogue was prepared by treating ethyl 3-(cyanomethyl)indole-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 - carbolines were obtained in a one-pot condensation. When cyclic ketones are used, the procedure allows a convenient synthesis of tetracyclic spiro compounds. Georg Thieme Verlag Stuttgart · New York.
