Asymmetric Hydrogenation of α,α′-Disubstituted Cycloketones through Dynamic Kinetic Resolution: An Efficient Construction of Chiral Diols with Three Contiguous Stereocenters
Chiral diols with threecontiguousstereocenters were synthesized by a highly enantioselective ruthenium‐catalyzedasymmetric hydrogenation of racemic α,α′‐disubstituted cycloketones involving dynamic kineticresolution. This new catalytic asymmetric method provides a concise route to the alkaloid (+)‐γ‐lycorane.
