T. Hashimoto et al., STRUCTURES OF A NOVEL BINAPHTHYL AND 3 NOVEL BENZOPHENONE DERIVATIVESWITH PLANT-GROWTH INHIBITORY ACTIVITY FROM THE FUNGUS DALDINIA-CONCENTRICA, Chemical and Pharmaceutical Bulletin, 42(7), 1994, pp. 1528-1530
A novel binaphthyl (1) and three novel benzophenone derivatives (2-4)
have been isolated from the fungus (Ascomycetes) Daldinia concentrica.
Their structures have been established by a combination of high resol
ution NMR spectra, X-ray crystallographic analysis and chemical degrad
ation. Compounds 2 and 3 possess plant-growth inhibitory activity.
