Across bonds: The first successful iridium‐catalyzed asymmetric hydroalkynylation of nonpolar alkenes with good to excellent enantioselectivity is described (see scheme; cod=1,5‐cyclooctadiene, DCE=1,2‐dichloroethane). This catalytic system exhibits good functional group compatibility as NH2, OH, Br, F, and SiMe3 groups remain intact during the reaction.
交叉键:描述了首次成功的具有良好对映选择性的非极性烯烃的铱催化不对称加氢烷基化反应(见方案; cod = 1,5-环辛二烯,DCE = 1,2-二氯乙烷)。该催化体系表现出良好的官能团相容性,因为在反应过程中NH 2,OH,Br,F和SiMe 3基团保持完整。
