Abstract
1286659 6,9,21-Trihalogenosteroids SCHER - ING AG 30 Sept 1969 [2 Oct 1968] 48004/69 Heading C2U Novel steroids of the formula (where X is F, Cl or Br and Y is Cl or F) are prepared by adding HOCl or HOBr to the corresponding 9,11 - unsubstituted - 9(11) - dehydrosteroids and, when the 9α-fluoro compounds are required, converting the products to 9,11)1- epoxides and splitting these with HF. Starting materials of the formula are prepared from 6α -fluoro - 21 - hydroxy - 16α- methyl - #<SP>1,4</SP>'<SP>9(11)</SP> - pregnatriene - 3,20 - dione (prepared by hydrolysis of the corresponding 21-acetoxy compound) by converting this to the 21-mesylate and then reacting this with KHF 2 or LiCl or by converting it directly to the 21- chloro compound using SOCl 2 in pyridine. The novel steroids are anti-inflammatory agents with slight diuretic activity and they may be made up into pharmaceutical compositions with suitable carriers.
