Disclosed are process steps and novel processes for producing chromane compositions enriched in at least one (2R or 2S) enantiomer, preferably chroman-2-yl carboxylic acid compounds and chroman-2-yl carboxylic acid esters which are intermediates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors. Further disclosed are enzymatic processes for resolving chiral intermediates or final products to provide desired enantiomers.
