Abstract

In 2013, brazilian researchers isolated the compound responsible for possible neurotoxic effects caused by the ingestion of star fruit (Averrhoa carambola) - the caramboxin. The structure contains a phenylalanine skeleton and the absolute configuration of carbon alfa-amino acid has only been inferred by comparison with the alfaD values of L-phenylalanine.To confirm the absolute configuration, this project proposes two studies to asymmetric total synthesis of caramboxine. In both studies, we will consider the 3,5-dihydroxybenzoic acid as starting material. The best route is evaluated in terms of performance and cost: or by diastereoselective alkylation of a glycine derivative (SCHOLLKOPF method) or through the Erlenmeyer-Plöchl reaction followed by enzymatic resolution of the amino acid.
