Abstract
A new synthesis of 1H-benzo[ b ]furo[3,2- f ]- and 1H-benzo[ b ]furo[2,3- e ]indoles was described. The corresponding ring-fused isatins, synthesized by the Sandmeyer reaction, were utilized as initial compounds. The reduction of the last to the unsubstituted benzo[ b ]furoindoles depends both on the nature of the substituent, and on the reaction conditions. Authors: T. O. Dzhashi, T. E. Khoshtariya, L. N.
