Transformations of Terpenoids on Acidic Clays

The review considers the intra- and intermolecular transformations of terpenes and their oxygen-containing derivatives in the presence of acidic clays. Using clays as catalysts of terpenoid transformations leads to improved characteristics of known processes and often to reaction routes other than those that occur in the presence of the traditional acid catalysts. This opens up new prospects for the application of renewable plant raw materials in fine organic chemistry.
