A microwave-promoted one-pot Claisen-rearrangement / 6-endo-trig cyclization yields allylflavanones, which undergo selective cross metathesis reactions with 2-methyl-2-butene to furnish prenylated flavanone natural products. One example is maximaflavanone, a secondary metabolite isolated from the Indian medicinal plant Tephrosia maxima.
