摘要:
Asymmetric synthesis of methyl 2-alkyl-3-hydroxybutanoate having three consecutive chiral centers with a reductase from bakers' yeast has been investigated. When the enzyme is employed in the reduction of a beta-keto ester substituted by a secondary alkyl group at alpha-position, the reaction affords the corresponding beta-hydroxy ester in excellent stereoselectivity.
