GUZMAN, M; ORTEGA, P; VERA, L  and  ASTUDILLO, E. Oxime-Derivatives of Dihydroeuparin. J. Chil. Chem. Soc. [online]. 2005, vol.50, n.1, pp.383-388. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072005000100003.

The synthesis of derivatives of dihydroeuparin, a secondary metabolite of the shrub Senecio graveolens, is described. The main modifications were the introduction of a hydrocarbon branch and the transformation of a ketone group into its oxime. Structure identification was carried out by IR, ¹H-NMR and ¹³C-NMR spectroscopy. These compounds may have application in the process of copper extraction
