ABSTRACT:
A method for the resolution of optically active compounds from racemic mixtures is provided. In one embodiment of the method, racemic substituted cyclopentenones, useful as eicosanoid intermediates, are enzymatically resolved with lipase and separated by formation of lithium salt complexes. In another embodiment of the method, optically active alcohols are obtained from prochiral halovinyl ketones or alkynyl ketones by selective catalytic reduction with chiral boronic catalysts. In yet another embodiment of the method, prostaglandin E.sub.1 are produced from prostaglandin E.sub.1 esters by selective ester hydrolysis with a lipase.
