Both enantiomers of modafinil, adrafinil, modafinic acid and ethyl modafinate were prepared from the diastereomers formed by reacting racemic β-sulfinyl carboxylic acid with (4R)-phenyl-thiazolidinethione. The absolute stereochemistry of the sulfoxide group was confirmed via X-ray analysis of one of the thiazolidinethione diastereomers.
