In view of the antitumor activity reported for 7,8-dimethylbenzo[b]azepine-2,5-dione, new isosteric thieno[2,3-b]-azepin-4-ones have been prepared by a Dieckmann ring closure reaction. Substituted 2-amino-3-carbethoxythiophenes were tosylated, or benzoylated, and the corresponding sodium salt was alkylated with ethyl 4-bromobutyrate. The resulting product
