| titleOfInvention | Processes for the preparation of 13-alkyl-gonapentaenes |
| abstract | 1,204,921. 13-Alkyl-gonapentaenes. ROUSSEL-UCLAF. 23 Aug., 1967 [25 Aug., 1966; 25 Nov., 1966; 7 July, 1967], No. 38828/67. Heading C2U. Optically active compounds of formula (wherein R is C 1-3 alkyl in the α- or #-configuration and the 3-alkoxy group has 1-10 carbon atoms), which compounds may bear additional nuclear substituents, are prepared by the action of a cyclization agent on the corresponding optically active 3-alkoxy-17,17-alkylenedioxy- 13 - alkyl - 9,10 - seco - gona - 1,3,5(10),8(14) - tetraen-9-ones (wherein the alkylene group has 2-4 carbon atoms and is optionally substituted) or on the magnesium complexes obtained by reacting an optically active 3-(1-alkyl-2,2- alkylenedioxy - 5 - hydroxy - 4 - cyclopentenyl)- propionic acid lactone with a 3-(m-alkoxyphenyl)-propyl magnesium halide. 19 - Nor - testosterone and its 13# - ethyl homologue are prepared from 3-methoxy-estra- 1,3,5(10),8,14-pentaen-17-one and its 13#-ethyl homologue via 3-methoxy-estra-1,3,5(10),8-tetraen-17-one and its 13#-ethyl homologue. |
