Abstract

AbstractThe enantioselective synthesis of zealexin A1, a sesquiterpene phytoalexin isolated from maize Zea mays is described for the first time. Our methodology for the total synthesis of zealexin A1 involved the stereoselective construction of the stereogenic center via enzymatic resolution followed by Johnson–Claisen rearrangement. The absolute configuration of the natural product was determined through gas chromatography analyses for the methyl esters for both synthetic and natural zealexin A1.
