          Abstract

          Usando reações clássicas como esterificação e oxidação, uma série de derivados foi obtida a partir da mistura alfa- e beta-amirina, constituintes majoritários da resina de Protium heptaphyllum. Os compostos obtidos foram caracterizados por dados espectroscópicos como: IV, RMN de ¹H e de 13C e comparação com dados da literatura.

          Translated abstract

          Using classic reactions such as esterification and oxidation, a series of derivatives was obtained from the alpha- and beta-amyrin mixture, major compounds of the Protium heptaphyllum resin. The obtained compounds were characterized by spectroscopic data such as: IR, ¹ H and 13C NMR and comparison with literature.
