<P><B>Abstract</B></P><P>The use of ene‐reductase (ERED) enzymes for the asymmetric reduction of olefins offers a green, renewable alternative to metal‐catalysed asymmetric reduction. We report herein the first example of an ERED‐catalysed enantiospecific reduction carried out at large scale using a carbonyl reductase (CRED) enzyme in the cofactor recycle. This reaction has been paired with a hydrolase‐mediated regioselective ester hydrolysis to generate a valuable chiral building block using a straightforward one‐pot process.</P>
