Enoate reductases from the ‘old yellow enzyme’ family were employed for the asymmetric bioreduction of methyl 2-hydroxymethylacrylate and its O-allyl, O-benzyl and O-TBDMS derivatives to furnish (R)-configurated methyl 3-hydroxy-2-methylpropionate products in up to >99% ee Variation of the O-protective group had little influence on the stereoselectivity, but a major impact on the reaction rate.
