Abstract

A new pathway has been proposed for the synthesis of dioxodihydro-1H-benzo[b]thiophenoindoles from the corresponding isomeric "amino acids" with amino groups at C(2) and C(3). This method yields these tetracyclic systems not only as a single isomer but  also permits their interconversion. Linear isomers may be obtained from angular tetracyclic systems and, vice versa, the isomer with angular fusion of the pyrrole ring may be obtained from the linear isomer. The classical Sandmeyer reaction was used as a model for such conversions.
