Synthesis of thieno[2.3—f]quinolines
Catalytic hydrogenation of 2.3-dihydro-thieno[2.3−f]-quinoline-1.1-dioxide yielded 22.214.171.124.8.9-hexahydrothieno-[2.3−f]quinoline-1.1-dioxide, which was substituted via the corresponding chloroacyl compounds to several 6-aminoacyl-derivatives.Skraup's synthesis using 6-amino-2.3-dihydro-3-morpholino-benzo[b]thiophen-1.1-dioxide gave 2.3-dihydro-3-morpholino-thieno[2.3−f]quinoline.
