Abstract:
Sulfur containing heterocyclic compds. (I; R is formula II; R1,R2,R3 = any combination of H, halogen, lower alkyl, phenyl, lower alkanoyl, or sulfamoyl etc. ; R4 = H, lower alkyl group ; R5,R6,R7 = H, halogen, lower alkyl, or lower alkoxy etc. X = sulfur, SO,SO2 ; Y = hydroxy group substituted C2-8 aliphatic group; Z = hydroxy group substituted C1-8 aliphatic group; m = 0,1; n = 2,3) and its acid added salts, useful for treating angina pectoris, were pred. by treating, e.g., compd. (III) with compd.(IV).
