isomers of naphthalenetricarboxylic acids have been synthesized by the oxidation of trimethylnaphthalenes, dimethylacetonaphthones, dimethylnaphthoic acids, methylnaphthalenedicarboxylic acids, β-(dimethylnaphthoyl)propionicacid, or β-(acenaphthoyl)propionicacids with aqueous sodium bichromate or potassium ferricyanide. Most of these naphthalenetricarboxylic acids, acid anhydrides, and trimethyl esters

The invention relates to a chiral selector useful in separating underivatized enantiomers of nonsterodial anti-inflammatory agents, particularly naproxen and other arylacetic acid compounds, and relates to a process for achieving such separation utilizing the chiral selector, which is also useful in achieving the enantiomeric separation of amines, alcohol derivatives, epoxides and sulfoxides. The invention is also directed to an apparatus which comprises the chiral selectors.
