Syntheses of dinor-cis/iso-12-oxo-phytodienoic acid (dn-cis/iso-OPDAs), ancestral jasmonate phytohormones of the bryophyte Marchantia polymorpha L., and their catabolites

Abstract

In recent years, the biology of the evolutionary origin of phytohormone signaling has made significant progress. Among them, the ligand-receptor co-evolution found in jasmonate signaling has attracted the attention of plant scientists. Dinor-cis-12-oxo-phytodienoic acid (dn-cis-OPDA, 4) and dn-iso-OPDA (5) are ancestral plant hormones of the bryophyte Marchantia polymorpha L. We succeeded in the first practical synthetic supply of these hormones as well as their possible catabolites. These compounds are expected to be useful in the study of ancestral jasmonate signaling in bryophytes.
