    Abstract: 1288414 Steroid 21-cyclobutane esters FARBWERKE HOECHST AG 22 Sept 1969 [20 Sept 1968] 46559/69 Heading C2U The invention comprises compounds of formula represents (i) a Y . . . C 9 -C 11 =X group where Y is H or F and X is H 2 , OXO, H(#-OH), H(α-OH), H(#-Cl) or H(#-F), or group; R 1 represents H 2 , H(α-Me), H(#-Me), H(α-F), H(#-F), CH 2 , CHF or CF 2 ; R 2 represents H or OH; R 3 represents a direct bond or a C 1-5 divalent aliphatic hydrocarbon group; and R 4 represents a cyclobutyl group which is substituted by at least one fluorine atom and which may be further substituted by one or more methyl groups and/or chlorine atoms. Preparation of the above compounds is from the corresponding steroid 21-ols by reaction with a compound of formula Cl-CO-R 3 -R 4 . Product interconversions specified are 1,2- and/ or 6,7-dehydrogenation; 6-, 9-, 11- and/or 16- fluorination; further fluorination of the cyclobutane ring; and reduction of 11-oxo to 11- hydroxy. The inventive compounds are stated to possess anti-inflammatory activity and may be made up with carriers into pharmaceutical and veterinary compositions for topical administration.

    Abstract: 1,228,069. Cardenolide ethers. FARBWERKE HOECHST A.G. 2 April, 1969 [6 April, 1968], No. 17192/69. Heading C2U. The invention comprises compounds of formula wherein R 1 is x-H, #-H or #-OH; R 2 , R 3 and R 4 are each H or OH; and R 5 is C 1-3 alkyl; and their preparation by LiAlH 4 reduction of compounds of formula wherein R 6 is C 1-3 alkyl and R 7 is CH 3 , CH 2 OH or CHO. A starting material with R 7 = CHO yields a product with R 2 = OH. Compounds of Formula II are prepared from the corresponding 3-hydroxy steroids by reaction with appropriately substituted dihydropyrans. Compounds of Formula I are stated to possess inotropic, cardiovascular, diuretic and anti-diarrhoeal effects, and may be made up with carriers into pharmaceutical compositions for oral administration.

    Abstract: 1,172,237. # 14 -21 -Acyloxy-pregnenes. FARBWERKE HOECHST A.G. 19 Dec., 1966 [18 Dec., 1965], No. 56726/66. Heading C2U. A # 14 - 3,20 - diketo - 21 - acyloxy - 5#- pregnene or a # 4,14 -3,20-diketo-21-acyloxypregnadiene is obtained by reacting a 3,20- diketo - 15α,21 - dihydroxy - 5# - pregnane or a # 4 - 3,20 - diketo - 15α,21 - dihydroxy - pregnene with a sulphonic acid halide, treating the 15α,21 - disulphonate or 15α - disulphonate- 21-halide so obtained with an alkali metal salt of a carboxylic acid in the presence of an organic solvent, and treating the resulting 21- acyloxy-15α-sulphonate with an agent capable of splitting off sulphonic acids.
