Abstract

508,804. Cyclopentanopolyhydrophenanthrene compounds. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Jan. 5, 1938, No. 318. [Class 2 (iii)] Aluminium alcoholate is used as either an oxidizing or a reducing agent for 3-hydroxy-, or 3-keto-compounds of the cyclopentanopolyhydrophenanthrene series in which there is at the 17-position a side chain containing a basic nitrogenous group. It is stated that the nitrogenous group does not take part in the reaction, but remains unchanged If desired, this group may be split off after the oxidation or reduction. In examples : (1) 3-hydroxy-ternoroholenylamine is oxidized to the corresponding 3-ketocompound by boiling with tertiary aluminium butylate in benzene solution in the presence of acetone ; (2) 3 - hydroxy - androstenmethylketimine prepared from acyloxyternorcholenylchloramine by the action of sodium alcoholate in alcohol solution, is oxidized to the corresponding 3-keto-compound by treatment as in example (1). ). The ketimine group is hydrolysed after the oxidation by treatment with N /2 sulphuric acid ; (3) 3-oxo-ternorcholenylamine is reduced with aluminium isopropylate in isopropyl alcohol solution to the corresponding 3-hydroxy compound. Specifications 487,360 and 500,186 are referred to.
