Abstract
1,138,247. Derivatives of oleanolic acid- BIOREX LABORATORIES Ltd. 11 Aug., 1967 [26 Aug., 1966], No. 38422/66. Heading C2C. Novel compounds of formula (wherein R is C 1-6 alkylene, and R 1 and R 2 are hydrogen or C 1-6 alkyl) and derivatives thereof containing an 11-oxo group or an additional double bond at 9(11), are prepared by reacting oleanolic acid or an alkyl ester thereof with the anhydride of an acid of formula (for products wherein R 1 is hydrogen) or with a compound of formula (for products wherein R 1 is alkyl). The 11-oxo groups or 9(11)-double bond may be introduced subsequently in known manner or alternatively may be present in the starting compound. In addition, the hydrolysis of products wherein R 1 and R 2 are both methyl to products wherein they are both hydrogen, is exemplified.
