title: A new compound from liquid fermentation broth of Armillaria mellea and the determination of its absolute configuration.
abstract: A new 2,5-diketopiperazine, (R)-2-(2-(furan-2-yl)-oxoethyl)-octahydropyrrolo[1,2-a]pyrazine-1,4-dione, and seven known compounds were isolated from the ethyl acetate extract of liquid fermentation broth of Armillaria mellea. The structures of the isolated compounds were established from NMR and HR-MS data. The absolute configuration of the new compound was established by comparing the experimental electronic circular dichroism (ECD) spectrum with the calculated ECD data.
