| titleOfInvention | Compounds of the cyclopentanopolyhydrophenanthrene series and a method of making same |
| abstract | The invention comprises compounds of the general formula <FORM:0738631/IV (b)/1> which represents a cyclopentanopolyhydrophenanthrene ring system having the <FORM:0738631/IV (b)/2> grouping in the 3-position and a keto group in the 17-position, and wherein R is a saturated or unsaturated aliphatic hydrocarbon residue. The compounds are prepared by oxidation of the corresponding 17-hydroxy derivatives. In examples: (1) 3a-methyl-androstan-3b : 17b -diol is oxidized with chromic acid in glacial acetic to yield 3a - methyl - androstan - 3b - ol - 17 - one; (2) 3b-methyl-androstan-3a : 17a -diol is oxidized as in (1) to produce 3b-methyl-androstan-3a-ol-17-one. The compounds obtained exhibit anti-hormonal activity. Specification 738,576 is referred to. |
