摘要

(S)-Selective kinetic resolution was achieved through the use of a commercially available protease,which was activated with a combination of two different surfactants.The kinetic resolution (KR) process was optimized with respect to activation of the protease and to the acyl donor.The KR proved to be compatible with a range of functionalized sec-alcohols,giving good to high enantiomeric ratio values (up to >200).The enzymatic resolution was combined with a ruthenium-catalyzed racemization to give an (S)-selective dynamic kinetic resolution (DKR) of sec-alcohols.The DKR process works under very mild reaction conditions to give the corresponding esters in high yields and with excellent enantioselectivities.
