Using the Knoevenagel reaction condensation products of 3β-acetoxyandrost-5-en-17-one with diethyl malonate, ethyl cyanoacetate and malononitrile were prepared which converted to derivatives of 3β-hydroxypregn-5-en-21-oic acid. Reductions and oxidations of the double bonds in the positions 5,6 and 17,20 and the stereochemistry at atoms C(17) and C(20) of some derivatives were also investigated. From derivatives of 23,24-dinorchola-5,17(20)-diene-21,22-diol compounds with a 1,3-dioxane ring in the side chain were prepared.

4-Chloromethyl-s-hydrindacene (VIIa) was transformed via the malonic acid derivatives VIIIa and IXa to the acid Xb which afforded in four steps the homological acid Xc. Reactions of chlorides of both acids (XIbc ) with dimethylamine, 1-methylpiperazine and 1-(2-hydroxyethyl)piperazine led to the amides XIIbc-XIVbc which were reduced with lithium aluminium hydride to the title compounds IVcd-VIcd. The amines obtained show central neuroleptic effects only in subtoxic doses; they are also potent local anaesthetics and have significant spasmolytic activity of the neurotropic as well as musculotropic type.
