title: Murayalactone, a dibenzo-alpha-pyrone from Streptomyces murayamaensis.
abstract: Murayalactone, 6, has been isolated from Streptomyces murayamaensis, and its structure assigned with the use of inverse nmr spectroscopy. This constitutes the first occurrence of a dibenzo-alpha-pyrone in a Streptomyces species, and the first biogenesis of this ring system from a decaketide.
