Abstract
The invention comprises 17-methyl-18-nor-Dhomoetiocholane-3, 11-dione derivatives having the formula: <FORM:0943957/C2/1> where X and Y together represent a double bond, Z represents a hydrogen atom and R represents either the oxygen atom of a keto group or cyclic ketal thereof; or X represents a hydrogen atom and either Y and Z together represent a double bond and R represents either the oxygen atom of a ketone group or a cyclic ketal group thereof or alternatively Y and Z together represent an ozonide linkage between the 16- and 17-position and R is the oxygen atom of a keto group and processes for the production thereof by reacting a 17-halogeno-17-methyl-18-nor-D-homoetiocholane-3, 11-dione with a lithium halide/lithium carbonate couple in an inert solvent thereby to form a mixture of the D 16 and D 17 isomers of 17-methyl-18-nor-D-homoetiocholene-3, 11-dione and if desired reacting this compound with ozone to form the 16, 17ozonide thereof. Separation of the D 16 and D 17 isomers may be effected by ketalising the mixture, separating the ketals thus obtained and recovering the desired compound from the appropriate ketal. Specifications 832,244 and 943,956 also are referred to.
