    Multi-Component Regio- and Diastereoselective Cobalt-catalyzed Hydrovinylation/Allylboration Reaction Sequence
    摘要:
    The combination of a regloselective cobalt-catalyzed 1,4-hydrovinylation and the dlastereoselective allyiboronation reaction leads to a wide scope of functionalized hydroxydienyl esters In a one-pot reaction in excellent yields. With catalytic amounts of base, these products are easily converted either into alpha,beta,gamma,delta-unsaturated hydroxyl esters or complex tetrasubstituted tetrahydropyrans In chemo- and diastereoselective fashions. In addition, a high-yielding four-component one-pot reaction involving an acrylate, two different and unsymmetrical 1,3-dienes, and an unsaturated aldehyde Is presented.

    Herein we disclose an asymmetric allylation of 3-hydroxyisobenzofuran-1(3H)-ones with boron allylation reagents to construct chiral phthalide derivatives. The simple Bi(OAc)3/chiral phosphoric acid catalytic system proves to be efficient in this method, delivering the desired chiral 3-allylisobenzofuran-1(3H)-ones in good yields (up to 99%) and high enantioselectivities (up to 99.5:0.5 e.r.) under mild
