Abstract

Several analogues of GR24 with modifications in the ABC part of the molecule were prepared from simple esters and lactones by α-formylation followed by coupling with a bromofuranone. The α-formyl derivative of 2-coumaranone was prepared in good yield via the corresponding α-ethorymethylene compound. Evaluation of the biological activity of the new analogues lacking ring B and/or C revealed that the ABC part of the GR24 molecule is not essential for germination stimulation of Striga and Orobanche seeds []
