    Enantioselective Redox-Neutral Coupling of Aldehydes and Alkenes by an Iron-Catalyzed “Catch–Release” Tethering Approach
    摘要:
    The reductive coupling of aldehydes and alkenes is an emerging technology that holds the potential to reinvent carbonyl addition chemistry. However, existing enantioselective methods are limited to form "branched" products. Herein, we present a directed enantio- and diastereoselective alkylation of aldehydes with simple olefins to selectively yield linear coupling products. This is achieved by redox-neutral remote functionalization, whereby a tethering "catch-release" strategy decisively solves the key problems of reactivity and selectivity.

    作者:Jun Takagi、Kou Takahashi、Tatsuo Ishiyama、Norio Miyaura
    DOI:10.1021/ja0202255
    日期:2002.7.1
    1-alkenylboronic acid pinacol esters via a palladium-catalyzed cross-coupling reaction of bis(pinacolato)diboron (pin(2)B(2), pin = Me(4)C(2)O(2)) with 1-alkenyl halides or triflates was carried out in toluene at 50 degrees C in the presence of KOPh (1.5 equiv) and PdCl(2)(PPh(3))(2)-2Ph(3)P (3 mol %). The borylation of acyclic and cyclic 1-alkenyl bromides and triflates was achieved in high yields with complete

  • Tandem Brønsted Acid Promoted and Nazarov Carbocyclizations of Enyne Acetals to Hydroazulenones
    作者:Luz Escalante、Carlos González-Rodríguez、Jesús A. Varela、Carlos Saá
    DOI:10.1002/anie.201205823
    日期:2012.12.3
    Ring the changes: Enyne acetals were easily converted into hydroazulene skeletons by a new and efficient metal‐free route involving a Brønsted acid promoted carbocyclization and a subsequent stereospecific Nazarov cyclization (see scheme). The versatility of this transformation also allowed assembly of interesting heteroaromatic tricyclic systems.

  • Alkenyl Bromides by Brominative Deoxygenation of Ketones in One or Two Steps
    作者:Ulrich Von Roman、Jakob Ruhdorfer、Rudolf Knorr
    DOI:10.1055/s-1993-25986
    日期:——
    The conversion of ketones into alkenyl bromides is accomplished in one or two steps by 2,2,2-tribromo-2,2-dihydro-1,3,2-benzodioxaphosphole or by the dibromomethyl methyl ether prepared therefrom. Investigations of the scope and limitations provide some hints for the preparative planning and improvement.

However, the transition-metal-catalyzed reaction has not been successful due to poor selectivity and very limited substrate scopes. We report here the efficient and selective 1,4-hydrosilylation of branched 1,3-enynes enabled by the ene-diamido rare-earth ate catalysts using both alkyl
