## Abstract Pyridoβanellated compounds analogous to tricyclic 1,4βbenzothiazine derivatives were synthesized. Thus, under mild reaction conditiones substitution of thiolactim **3** with different __N__βnucleophiles yielded the precursors for compounds, which were cyclized in a further step to the c
