A new monoterpene lactone from the acarid mite, Schwiebea araujoae, was elucidated without its isolation by GC/FT-IR and GC/MS analyses to be 3- (4-methyl-3-pentenyl) -2 (5H) -furanone (1) and tentatively named as α, α-acariolide. The structure of 1 was identified by its synthesis from α-bromo-γ-butyrolactone via 4 reaction steps. The synthesized compound gave the same GC/MS and GC/FT-IR spectra as those of the natural product. The other monoterpene lactone was likewise elucidated from the unidentified Rhizoglyphus mite to be 4- (4-methyl-3-pentenyl) -2 (5H) -furanone (2) and named as α, β-acariolide ; it was also identified by its synthesis in 5 reaction steps from the same butyrolactone as the starting material. GC/MS and GC/FT-IR spectra of the preparation were identical to those of the natural product.
