Structure and absolute configuration of the asticolorins, toxic metabolites from Aspergillus multicolor
Abstract
The structure elucidation of asticolorins A–C, toxic metabolites isolated from cultures of Aspergillus multicolor, is based on X-ray crystallography of asticolorins A (1) and on a betailed study of their 1H and 13C n.m.r. spectra; the chirality of the C-29 Secondary hydroxy group present in asticolorin A, as determined by the method of Horeau, established the absolute configuratgion.
