A range of analogues of the natural germination stimulant, strigol, for parasitic weeds of the genera Striga and Orobanche, has been prepared. Most of the products contain an a-formyl-7-lactone (or a-formyl-7-lactam) grouping attached through an enol-ether linkage to the 5-position of a but-2-enolide. Some have shown sufficiently high activities as to warrant large-scale field trials
