Benzomorphan related compounds. V (1). Synthesis of thienomorphans
A series of thieno[2,3-f]-, [3,2-f]- and [3,4-f]morphans prepared both by the Grewe synthesis and by the reaction of 2-cyanopyridines with 3-thienyllithium is described. Furthermore, a new synthetic route to thieno[2,3-f]morphans from 3-ketotetrahydrothiophene is reported. Separation and assignment of the alpha- and beta-diastereomeric structures by means of nmr data is reported. Some side products were isolated and their structures were confirmed on the basis of their spectral data. Mechanisms for their formation are proposed.
