A new yellow pigment, designated acetosellin 1, was isolated from the mycelium of Cercosporella acetosella as a reduced azaphilone metabolite. The structure of I was determined by spectroscopic investigations and chemical evidence. Compound I possesses a novel carbon skeleton that of a naphtopyrane derivative, linked to an extensively conjugated chain.

Abstract
A new yellow pigment, designated acetosellin 1, was isolated from the mycelium of Cercosporella acetosella as a reduced azaphilone metabolite. The structure of I was determined by spectroscopic investigations and chemical evidence. Compound I possesses a novel carbon skeleton that of a naphtopyrane derivative, linked to an extensively conjugated chain. The absolute configuration was determined by NOE experiments and CD correlations.File in questo prodotto:
