摘要
Pestalachlorides A-C (1-3), three new chlorinated benzophenone derivatives, have been isolated from cultures of an isolate of the plant endophytic fungus Pestalotiopsis adusta. The structures of these compounds were determined mainly by NMR spectroscopy, and the structures of 1 and 3 were further confirmed by X-ray crystallography. Pestalachloride A (1) was obtained as a mixture of two inseparable atropisomers (1a and 1b), whereas pestalachloride C (3) was found to be a racemic mixture. Compounds 1 and 2 displayed significant antifungal activities against three plant pathogens. (C) 2008 Elsevier Ltd. All rights reserved.
