The present invention relates to a class of novel annulated 4H-1,4-benzothiazine derivatives of the formula wherein
R is hydrogen or a
group wherein R3 is C1-C15 alkyl;
R1 is hydrogen or C1-C3 alkyl;
R2 is phenyl or substituted phenyl containing one or two substituents selected from the class consisting of halo, hydroxy, trifluoromethyl, methoxy, cyano and C1-C4 alkyl; and
X and Y are independently hydrogen, halo, nitro, trifluoromethyl, amino or C1-C4 alkoxy.
Said derivatives are effective anorectic agents. In particular, certain of the novel annulated 4H-1,4-benzothiazine derivatives are effective anorectic agents when administered orally.
