Reliable Chiral Transfer Through Thermodynamic Equilibrium of the Intramolecular Meerwein‐Ponndorf‐Verley Reduction and Oppenauer Oxidation.

Forward and reverse hydride transfer with rigorous diastereodifferentiation is attained using intramolecular Meerwein–Ponndorf–Verley reduction and Oppenauer oxidation of a 2-acetylphenyl ether containing an optically active 3-hydroxy-1-methylbutyl group.
