    Abstract: Thienothiazine derivs. (I; A formed B or C with two carbons, R1 = lower alkyl, R2 = aromatic heterocyclic residues, Ph, R3, R4 = H, lower alkyl) useful as antiphlogistic, anodyne, and antirheumatic, were prepd. by treating I(NHR2 = OR, R - lower alkyl) with amine (III), decyclizing IV, lower alkylizing I(R' = H), reacting I(OH = O, COHNR2 = H2) with isocyanate (O = C = N-R2) in the presence of strong base, or hydrolizing enamines (I; OH = NR5R6, R5, R6 = lower alkyl).

    Abstract: Psychotropic thienotriazolodiazepines (I; n = o or 1, R1 = H, cl, alkyl, alkanoyl, amino group R2 = phenyl, o-halophenyl, o-nitrophenyl, R3 = H, hydroxy, alkoxycarbonyl, alkanoyloxy group, R4 = H, alkyl, alkanoyl, hydroxyalkyl, mercaptoalkyl, alkoxycarbonyl, alkylthioalkyl, alkylcarbonyloxyalkyl group) were prepd. by cyclizing the hydrazinothienodiazepines.I,2-chloro-4-(o-chlorophenyl)-9-methyl-6H-thieno-{3,2-f -s-triazolo [4,3-al [1,4 diazepine showed ED50= 1 mg/kg orally in the chimney test of mouse.
