Abstract

Total synthesis of two arabidopyrones, iso-arabidopyl alcohol (1) and iso-arabidopic acid (2) isolated from Arabidopsis thaliana was achieved for the first time using Claisen condensation and Wittig reaction as the key steps. In addition, arabidopic acid (4) was synthesized from the methyl ester of arabidopyl alcohol (3). Thus, chemical synthesis of the unique natural α-pyrones 14 was accomplished with a short synthetic route by a systematic approach from readily available substances.
