synthesis of carveol ,carvone,verbenol,and verbenone

Abstract

This paper presents a review on catalytic systems, reported between 1990 and 2007, for the synthesis of carveol, carvone, verbenol, and verbenone. These products are used in the pharmaceutical and food industries as raw materials for the production of fragrances and flavors. The increasing demand for these products and the worldwide trends to implement environmentally-friendly processes makes it necessary to maintain efforts in the search for catalytic synthesis systems that turn out to be economically and technically feasible. Emphasis is made on the allylic oxidation of limonene and a-pinene. Moreover, we present the most recent advances of our research group in the study of catalytic reactions based on phtalocyanines.
