Abstract

Influence of orthophosphoric acid on chemical transformations of betulinol in an acetic acid, butanol, and isobutanol was investigated. It was established that in the presence of orthophosphoric acid the transformation of betulinol in acetic acid medium occurs with formation of betulinol diacetate; in butanol and isobutanol medium the reaction of isomerization of betulinol into allobetulin takes place.
