Abstract

1,193,951. 13-C 2-4 alkyl-gonane compounds. H. SMITH. 18 Aug., 1967 [19 May, 1966], No. 22343/66. Heading C2U. Novel steriods of the structure wherein R<SP>1</SP> is C 2-4 alkyl; Y is CH(OH) or an ester or ether thereof or a corresponding group with the 17-hydrogen atom replaced by a substituted or unsubstituted alkyl, alkenyl or alkynyl group, CO or a ketal thereof, CH(COCH 2 OH) or an ester thereof, CH(CH.OH.CH 2 - OH) or a mono- or di-ester thereof, or CH(CO 2 H) or a halide thereof; W is CH(OH) or CO or a ketal thereof; and ring A can optionally contain at least one halogen, alkyl or ethoxalyl substituent, are prepared by reduction of the corresponding #<SP>4</SP>-, #<SP>5</SP>- or #<SP>5(10)</SP>-gonenes. This reduction may be followed by one or more of the following processes: acylation, hydrolysis, oxidation and reduction in the 17-side chain, reduction of a 3-one to a 3-ol, ketalization of a 3-one, conversion of a 2-unsubstituted-3-one to a 2-alkyl-3-one, via for example, the 2-ethoxalyl compound if the 2-methyl compound is required, etherification of a 17-ol, conversion of a 17-one to a 17α-hydrocarbon-17#-ol, and deketalization of a 3-ketal. Also the 21-hydroxy- 20-ones and -ols and their acylates can be prepared from the 21-unsubstituted, 20-ones or the 17-halocarbonyl compounds by known methods e.g. conversion of a 17-halocarbonyl compound to a 21-diazopregnan-20-one and hydrolysis or acylolysis of thio. The steriods are of the dseries but may also be in admixture with those of the l-series, including racemic mixture. The 13-C 2-4 -alkylgonane compounds of the invention, which may variously have minerals corticoid, anaesthetic, anabolic, blood lipid depressing and estrogen antagonist activity, may be made up into pharmaceutical compositions with suitable carriers.
