ABSTRACT:
Racemic mixtures of d,1-2-(6-methoxy-2-naphthyl)propanal are resolved by forming a condensation product with N-R-D-glucamine or a salt thereof where R is hydrogen, alkyl of 1 to 36 carbon atoms or cycloalkyl of 3 to 8 carbon atoms, from which a product substantially enriched in d-2-(6-methoxy-2-naphthyl)propanal can be obtained and then can be selectively oxidized to d-2-(6-methoxy-2-naphthyl)propionic acid.
