α,ω‐Functionalized 2,4‐Dimethylpentane Dyads and 2,4,6‐Trimethylheptane Triads through Asymmetric Hydrogenation

A match made in heaven: All the possible stereoisomers of α,ω-functionalized 2,4-dimethylpentane dyad and 2,4,6-trimethylheptane triad chirons (see picture; A and B, respectively; FG=functional group, PG=protecting group) can be reached by using a combination of a chiral catalyst and substrate effects in the hydrogenation of mainly nonfunctionalized alkenes. Excellent diastereo- and enantioselectivities were achieved.
