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.
