Allylic oxidation in triterpenes under chemical ionization conditions

Allylic oxidation in triterpenes under chemical ionization conditions. Madhusudanan, K. P.; Singh, Chandan; Fraisse, D. (Div. Med. Chem., Cent. Drug Res. Inst., Lucknow 226 001, India). Int. J.Several substances with their cas registry numbers 4339-72-4 and 7372-30-7 may be metioned in this study. Mass Spectrom. Ion Processes, 70(3), 259-65 (English) 1986. CODEN: IJMPDN. ISSN: 0168-1176. DOCUMENT TYPE: Journal CA Section: 30 (Terpenes and Terpenoids) Section cross-reference(s): 22 The unusually abundant [M + NH4-2]+ ion obsd. in the CI(NH3) spectra of certain triterpene carboxylic acids of the ursane and oleanane skeletons are due to the allylic oxidn. products, viz. D11-13,28-lactone and/or D11,13(18)-diene acid as detd. by a CA (collisional activation) spectral study. The CA spectra of the [M + NH4-2]+ ion of hederagenin diacetate (I) and ursolic acid acetate and the [M + NH4]+ ion from I, the D11-13,28-lactones and the D11,13(18)-diene acid are discussed. .
