Enzymatic acylation of secondary symmetrical diols (as meso/dlmixtures) in combination with ruthenium-catalyzed isomerization of the diol led to efficient dynamic kineticresolution. In this way, a meso/dlmixture of the diol was transformed to enantiomerically pure (R,R)-diacetate, making efficient use of all the diol material. For some of the flexible substrates, substantial amounts of meso-diacetates
