New derivatives of pyrano[4″,3″:4′,5′]pyrido[3′,2′:4,5]thieno[3,2-d]pyrimidines based on 3-chloro derivatives of pyrano[3,4-c]pyridines and pyrano[4″,3″:4′,5′]pyrido[3′,2′:4,5]furo[3,2-d]pyrimidines based on previously prepared 8-chloro derivatives were synthesized. Studies of the biological activity of the synthesized compounds showed that several of them exhibited neurotropic properties.

Notes
Resonances for the 2,2-dimethylpyran ring practically did not differ from those of VIa; therefore, they are not given further.
