one-pot procedure to achieve efficient DYKAT of α-substituted β-hydroxyketones. This newly developed protocol offers straightforward access to enantiomerically pure and diastereomerically enriched β-oxoacetates in high yields by employing a ruthenium-based racemization catalyst for efficient racemization-epimerization of substrates via formation of non-chiral 1,3-diketone intermediates.
