The present invention relates to enantiomerically pure cis-3- (4,6-dihydroxychroman-3-ylmethyl) benzoic acid and a process for the preparation thereof. These compounds are optically pure mirror images of cis-3- (6-arylmethyloxy-4-hydroxychroman-3-ylmethyl) aniline sulfonamide useful for the treatment of asthma, arthritis, psoriasis, ulcers, myocardial infarction and related diseases. It is an intermediate compound useful for the preparation of isomers. More specifically, the present invention relates to (3R-cis) -3- (4,6-dihydroxychroman-3-ylmethyl) benzoic acid. The invention also relates to an improved process for the preparation of racemic cis-3- (4,6-dihydroxychroman-3 ylmethyl) benzoic acid.
