Project title: Model For Total Synthesis of Puraquinonic Acid
Project description (50-100 words suggested): Puraquinonic acid is an illudalane natural product which possesses mild HL-60 differentiation activity. We have previously reported a 12-step enantioselective synthesis of puraquinonic acid which used our bicyclic thioglycolate lactam alkylation chemistry (Organic Letters, 2006, 8, 1359) to set the key quaternary carbon stereocenter (Angew. Chem. Int. Ed. 2013, 52, 3442). In this project, the quaternary stereocenter was formed at the beginning of the synthesis and carried through the entire synthetic route. This project will examine a new route where the stereocenter is formed at the very end of the synthesis, which should, in theory, be more efficient. The goal of this project will be to study a model alkylation of a 2,3-dibromomethylarene (e.g., 2,3-bis(bromomethyl)-toluene) to see if the generation and alkylation of cyclic enolates can be accomplished using our methodology. If this is successful, the student will have the opportunity to begin the synthesis of the desired dibromoarene to prepare puraquinonic acid itself.
