A match made in heaven: All the possible stereoisomers of α,ω-functionalized 2,4-dimethylpentane dyad and 2,4,6-tri- methylheptane 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. (Chemical Equation Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
