摘要：

Stereoisomers of methyl ricinoleate, methyl isoricinoleate, and related methyl esters of bis-homoallylic hydroxy fatty acids were reacted with (R)- and (S)-alpha-naphthylethyl isocyanate to form diastereomeric carbamates that separated well on silica gel high-performance liquid chromatography. Proton nuclear magnetic resonance shifts of the carbomethoxymethyl protons were used to assign configuration to the alcohol component of the carbamate derivative. Combining high-performance liquid chromatography with proton nuclear magnetic resonance spectroscopy may allow one to determine the configuration of naturally occurring hydroxy fatty acids as well as to determine configurational purity.
