title: Six New Vibralactone Derivatives from Cultures of the Fungus Boreostereum vibrans.
abstract: Phytochemical reinvestigation on the cultural broth of Boreostereum vibrans led to the isolation of six new vibralactone derivatives, vibralactone N (1), vibralactone O (2), vibralactone P (3), 10-lactyl vibralactone G (4), (3S*, 4R*)-6-acetoxymethyl-2,2-dimethyl-3,4-dihydro-2H-chromene-3,4-diol (5), vibralactone Q (6). Their structures were elucidated by extensive spectroscopic methods.
