Olean-12-en-, 11-oxoolean-12-en, and 12-oxoolean[3,2-b]quinoline-28-oic acid methyl estres (3a-3c) were obtained from the respective 3-oxoderivatives 1a-1c through the C(2) o-nitrobenzylidene derivatives 2a-2c. It was observed that the C(3) carbonyl group had an activating effect on the neighbouring methylene function and the C(2) and C(12) carbonyl group in some derivatives of methyl oleanolate were deprived of this property.
