Abstract Conversion of the methyl ester of lesquerolic acid,(R)-14-hydroxy-Z-11-eicosenoic acid, to a carbamate with (S)-1-(1′-naphthyl) ethylisocyanate gave a single diastereomer. Comparisons of elution orders of the relevant diastereomers obtained from the racemic ester and from a sample of lesquerolic acid synthesized from ricinoleic acid,(R)-12-hydroxy-Z-9- octadecenoic acid, were consistent with the original assignment of (R)-configuration for ...
