Abstract

A method was developed for assignment of the absolute configuration of oxylipin-derived 2-hydroxy acids, 3-hydroxy acids and 2,3-dihydroxy acids. The monohydroxy acids were converted into diastereomeric (PAP) derivatives by coupling to the methyl ester of l-phenylalanine followed by propionylation, whereas the 2,3-dihydroxy acids were derivatized by treatment with l-phenylalanine methyl ester followed by acetone and perchloric acid, to afford diastereomeric (IAP) ...
