Structure and absolute configuration of acetosellin, a new polyketide from a phytotoxic strain of Cercosporella acetosella / G. Nasini, A. Arnone, G. Assante, G. Candiani, O. Vajna de Pava. - In: TETRAHEDRON LETTERS. - ISSN 0040-4039. - 43:1(2002), pp. 1665-1668.
Abstract:
A new yellow pigment, designated acetosellin 1, was isolated from the mycelium of Cercosporella acetosella as a reduced
azaphilone metabolite. The structure of 1 was determined by spectroscopic investigations and chemical evidence. Compound 1
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.
