    Abstract: 1435204 Cardenolide glycosides HOECHST AG 30 July 1973 [29 July 1972] 36141/73 Heading C2U The invention comprises cardenolide 3-(2- deoxy-α-L-glycosides) of formula wherein R 1 is a steroid-3-yl radical of the 20(22)- cardenolide series; R 2 is H, C 1-5 aliphatic carboxylic acyl or C 7-8 aromatic carboxylic acyl; and R 3 is H, Me or OH 2 OR 2 . Preparation is from the corresponding 3-(2,3-dideoxy-2(3)-dehydro - α - L - glycosides) (cf. Specification 1,268,230) by hydroxybromination to give 3-(2- bromo - 2 - deoxy - α - L - glycosides), catalytic hydrogenation of which yields compounds I which may be interconverted by saponification or acylation within the sugar moiety. Digitoxigenin 3 - (2,3 - dideoxy - 2(3) - dehydro- α-L-rhamnoside)-4 1 -acetate is prepared from digitoxigenin by reaction with diacetyl-L- rhamnal. Compounds I are said to possesss cardiotonic, diuretic, antidiarrhoeal and venous tonusimproving properties, and may be made up with carriers into pharmaceutical compositions for oral and parenteral administration.

    Abstract: 1323775 Cardial glycosides FARBWERKE HOECHST AG 1 Sept 1970 [29 Aug 1969(2)] 41722/70 Heading C2U The invention comprises compounds of formula where R is a steroid 3-yl radical of the 20(22)- cardenolide or 20,22-bufadienolide series; the two symbols R 1 together represent an epoxy group, or, when R is a cardenolide radical, they each may alternatively represent a hydrogen atom; R 2 is H or an aliphatic, cycloaliphatic, aromatic or araliphatic hydrocarbyl or acyl group; and R 3 is H, Me or CH 2 OR 2 . Preparation of compounds (I) is from compounds of formula by catalytic hydrogenation (for products wherein R 1 = H) or by reaction with an organic peracid (for products wherein R 1 +R 1 = epoxy). Subsequently any 4 1 -acyloxy group may be hydrolysed, or any 4 1 -hydroxy group esterified or etherified. Digitoxigenin 3 - (# 2 - 2,3 - dideoxy - 4 - O- acetyl - D - arabinoside) is prepared by reacting digitoxigenin with di-O-acetyl-D-arabinal. The L-arabinoside isomer is prepared analogously and then hydrolysed to digitoxigenin 3-(# 2 - 2,3-dideoxy-L-arabinoside). Uzarigenin 3 - (# 2 - 2,3 - dideoxy - 4 - O- acetyl-α-L-rhamnoside) is prepared by reacting uzarigenin with di-O-acetyl-L-rhamnal. Other starting materials of Formula II are prepared as described in Specfications 1,268,230, 1,282,019 and 1,323,148. The steroids of Formula (I) are stated to possess cardiotonic, diuretic and antidiarrhoeal activities, and may be made up with carriers into pharmaceutical compositions for oral or parenteral administration.

    Abstract: 1315235 Bufapolyenolides FARBWERKE HOECHST AG 19 April 1971 [8 April 1970] 26359/71 Heading C2U The novel compound 3#-(α-L-rhamnopyranosyloxy) - 14,15# - epoxy - 14# - bufa - 4,20,22- trienolide is prepared from proscillaridin by successively acylating the three sugar hydroxy groups, dehydrating in the 14,15-position, adding hypohalous acid acoross the resulting # 14 - double bond, dehydrohalogenating the resulting 14#-hydroxy-15α-halo grouping, and lastly liberating the three sugar hydroxy groups by saponification. The novel compound is stated to be cardioactive and may be made up with carriers into pharmaceutical compositions for oral administration.
