dimethoxy[1]benzothieno[2,3-c]quinolines have been prepared by photocyclization of the appropriate N-phenyl-3-chlorobenzo[b]thiophene-2-carboxamides. The lactams obtained were converted into the thiolactams and their S-methyl derivatives. The lactams were also converted into the corresponding chloro derivatives which were catalytically dechlorinated into the dimethoxy[1]benzothieno[2,3-c]quinolines. The
