Synthesis of new hetero1,2,4thiadiazin-3-one S,S-dioxides and Oxazolo3,2-bhetero1,2,4thiadiazine S,S-dioxides as potential psychotropic drugs

摘要

A series of 2-substituted 2H-thieno[3,4-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxides (2), 2-substituted 2H-thieno[2,3-e][1,2,4]thiadiazin-3(4H)-one 1,1-dioxides (3), 2-substituted 4,6-dihydropyrazolo[4,3-e]-[1,2,4]thiadiazin- 3(2H)-one 1,1-dioxides (4), 2-substituted 2,3-dihydrooxazolo[3,2-e]thieno[3,4-e] -[1,2,4]thiadiazine 5,5-dioxides, (5), 6-substituted 6,7-dihydro-2H-oxazolo[3,2- b]pyrazolo[4,3-e][1,2,4]thiadiazine 9,9-dioxides (6) and 7-substituted 6,7-dihydro-2H-oxazolo[3,2-e]pyrazolo[4,3-e][1,2,4]thiadiazine 9,9-dioxides (7) were synthesized as potential psychotropic agents.
