title: Absolute and relative configuration of erythroskyrin.
abstract: We have reisolated erythroskyrin from Penicillium islandicum and have determined the relative stereochemistry of the compound through extensive 1H- and 13C-nmr studies. The absolute stereochemistry was determined by nmr studies of the O-methylmandelate esters.
