Popis: The reduction of racemic β-keto esters having the tetralone structure by chiral ruthenium(II) catalysts is realized with an ideal kinetic dynamic resolution. Remarkably, high anti selectivity approaching 100% and enantioselectivity (up to 97%) using atropisomeric ligands are obtained. The trans β-hydroxy esters thus available are useful starting materials for production of enantiomerically pure compounds.
