Farinomalein
Chemical compound
From Wikipedia, the free encyclopedia
Farinomalein is a natural maleimide with formula C10H13NO4 - was first isolated from the entomopathogenic fungus Isaria farinosa (Paecilomyces farinosus) - source H599 (Japan).[1]

Farinomalein has shown potent and selective inhibition (0.15-5 μg/disk) against eight isolates of plant pathogenic Phytophthora sojae.[2] These results suggest that farinomalein might be useful as a candidate pesticide for the treatment of Phytophthora stem rot in soybean.[2]
Synthesis
A simple two-stage synthesis from the γ-hydroxybutenolide compound, 5-hydroxy-4-methyl-2-5(H)-furanone, has been reported.[3] Firstly, the furanone is oxidized to 3-isopropylfuran-2,5-dione by Dess–Martin periodinane, followed by acetic acid reflux with beta-alanine. The white powdered product has a melting point of 75-77 °C.
