Abstract: | Primary alcohols with an unfunctionalized stereogenic center in the β‐position undergo an enzyme‐ and metal‐catalyzed dynamic kinetic resolution (DKR). The in situ racemization of the primary alcohol, required for the DKR, takes place via: (i) ruthenium‐catalyzed dehydrogenation of the alcohol, (ii) enolization of the aldehyde formed, and (iii) ruthenium‐catalyzed readdition of hydrogen to the aldehyde. The present method widens the scope of metal‐ and enzyme‐catalyzed DKR, which has so far been limited to α‐chiral alcohol and amine derivatives. |
