Previously unreported p-terphenyl derivatives with antibiotic properties from the fruiting bodies of Sarcodon leucopus (Basidiomycetes). A Two-dimensional nuclear magnetic resonances study

Two previously unreported antibiotic metabolites, 2',3',4"-triacetoxy-3,4,5',6'-tetrahydroxy-p-terphenyl (10) and 2',3'- diacetoxy-3,4,5',6',4"-pentahydroxy-p-terphenyl (11), have been isolated from the basidiomycete Sarcodon leucopus. Their structures have been determined by chemical transformations and spectral analysis, including heteronuclear two-dimensional nuclear magnetic resonance methods.
