Pyrido‐anellated compounds analogous to tricyclic 1,4‐benzothiazine derivatives were synthesized. Thus, under mild reaction conditiones substitution of thiolactim 3 with different N ‐nucleophiles yielded the precursors for compounds, which were cyclized in a further step to the corresponding tricyclic derivatives.
