Iridium‐catalyzed asymmetric hydrogenations of chiral alkenes were used to access four pivotal α,ω‐functionalized chirons, that contain widely occurring stereochemical 1,2,3‐Me,OH,Me motifs. A chiral analogue of Crabtree’s catalyst was used in key hydrogenation steps to form these motifs with high stereochemical purities. An application of one of these chirons is illustrated here with a synthesis of
