In this study, an engineered carbonyl reductase (M4) was obtained through structure-guided directed evolution of a carbonyl reductase (SSCR) from Sporobolomyces salmonicolor AKU4429. Mutant M4 showed 23.9-fold enhancement of enzyme activity toward the model substrate 2-methyl-2-benzyl-1,3-cyclopentanedione, affording the (2S,3S)-stereoisomer in >98percent ratio. This variant also showed excellent stereoselectivity toward most of the tested substrates, offering a valuable biocatalyst for the stereoselective reduction of these cyclic diketones to access the corresponding (2S,3S)-2,2-disubstituted-3-hydroxyketones.

Highly enantioselective reduction of 1,3-cyclopentanediones was conducted using an oxazaborolidine derived from L-threonine and a borane complex to give either 1,3-cyclopentanediols or 3-hydroxycyclopentanones in high enantiomeric purity by choosing appropriate reduction conditions.
