γ-(6-Methoxy-2-carboxy-3, 4-dihydro-l-naphthyl)-butyric acid was reduced in the presence of 5% Pd-C to the saturated acid, γ-(6-methoxy-2-carboxy-1, 2, 3, 4-tetrahydro-1-naphthyl)-butyric acid, by the method of Bachmann and co-workers.From this reaction only one of the two diastereoisomers was obtained as the principal product.This acid was resolved into its optical antipodes with brucine in anhydrous methanol.
