Chiral sulfinyl esters are an essential source for preparation of chiral sulfur-containing fine chemicals and pharmaceuticals. However, sustainable enantioselective syntheses optically pure remain to be explored. Herein, we have developed methionine sulfoxide reductase A (MsrA) variants with expanded substrate scope using in silico docking semirational mutagenesis techniques, aimed at preparing enantiopure esters. The variant paMsrA-F59A exhibited exceptional activity enantioselectivity across various esters, yielding the R enantiomers approximately 50% yield 99% enantiomeric excess. Furthermore, this overcame significant limitation wild-type (WT) MsrA, broadening its from methyl ethyl substituents n-propyl/butyl ester substituents. Afterward, by employing conjunction oxidase styrene monooxygenase (SMO), achieved cyclic deracemization racemic obtaining a series (R)-sulfinyl >90% This study successfully providing environmentally friendly strategy efficiently Moreover, our extended application MsrA synthesis compounds bulkier frameworks, highlighting potential green chemistry applications.
