The invention provides a new enzimatic process for the preparation of chiral carboxylic acids, their salts and acid derivatives of the general formula (I) by enzymatic hydrolysis of racemic carboxylic acid ester of the general formula (II) and optionally subsequent esterification or acylation.
The presently disclosed subject matter provides methods of preparing synthetic prostacyclin analogues, including Beraprost, either as racemic mixtures or as single stereoisomers. Also provided are novel synthetic intermediates for use in these methods.
