Total Synthesis of Sordaricin [PDF]

open access: yesThe Journal of Organic Chemistry, 2003
An enantioconvergent total synthesis of sordaricin (3), the diterpene aglycon of an important class of antifungal compounds, is described. Two approaches were explored, the first of which utilized a possible biogenetic intramolecular [4 + 2] cycloaddition to form the complete carbon skeleton of the target molecule as a single regioisomer 30.
