  • Nickel‐Catalyzed, Regio‐ and Enantioselective Benzylic Alkenylation of Olefins with Alkenyl Bromide
    作者:Jiandong Liu、Hegui Gong、Shaolin Zhu
    DOI:10.1002/anie.202012614
    日期:2021.2.19
    A NiH‐catalyzed migratory hydroalkenylation reaction of olefins with alkenyl bromides has been developed, affording benzylic alkenylation products with high yields and excellent chemoselectivity. The mild conditions of the reaction preclude olefinic products from undergoing further isomerization or subsequent alkenylation. Catalytic enantioselective hydroalkenylation of styrenes was achieved by using

    towards the synthesis of epoxydiynes which represent an unusual structural feature of the neocarzinostatin chromophore. A number of different routes to these epoxydiynes have been explored with varying success. Ultimately a concise and convergent approach was developed, which involved the addition of an allenyl zinc bromide to propargylic ketones/aldehydes followed by epoxide formation. This new protocol
