Research: Synthesis of Natural Products

Our main interest is the synthesis of biologically active natural products. Abscisic acid (a vegetal hormone) and Artemisinin (a strong anti-malaria agent) are illustrative examples of substances already synthesized in our laboratory.

We are presently developing methods for the synthesis of goyazensolide, of products extracted from Otoba parvifolia, of microbiotol, etc. See under Current Research for more details.

We do also some investigations on novel organic reactions, analytical methods and development of software and equipment for research and educational purposes. See under Software some of the programs we have developed as part of our research work.
