Pyrrolo(2,3-b)indole-ketones of formula (I), their acid addn. salts, geometric and optical isomers and racemic mixts. are new. In (I), R1 = lower alkyl, aryl or aryl-lower alkyl; R2 = H, halogen or lower alkyl; R3 = H or lower alkyl; R4 = lower alkyl or aryl-lower alkyl; R5 = H, lower alkyl, lower alkenyl, lower alkynyl, aryl lower alkyl, -CHO, lower alkylcarbonyl, aryl-lower alkylcarbonyl or lower alkoxy. Specifically claimed is 1-(1,2,3,3a,8,8a-hexahydro-1,3a, 8-trimethylpyrrolo(2,3-b)indol -5-yl) -2-propanone, di-toluoyl-L-tartaric acid salt (Ia). |
