要旨:
Diastereomers made to order: In an unprecedented ligand-controlled process a racemic mixture of four stereoisomers can be converted with high selectivity into each one of the diastereomers of the product, at will (see scheme). The mechanism of this deracemization of epimers, that is, a de-epimerization, was also studied.
