    Synthesis of 3-Substituted Benzo[b]thiophenes via the Reaction of α-Substituted 2-Lithio-β-methoxystyrenes with Sulfur
    摘要:
    3-Substitued benzo[b]thiophenes were synthesized in reasonable overall yields from alpha-substituted 2-bromo-beta-methoxystyrenes. Thus, the bromine-lithium exchange between these bromostyrenes with butyllithium in diethyl ether at 0 degrees C followed by reaction with sulfur afforded the corresponding a-substituted beta-methoxy-2-sulfanylstyrenes. These were then treated with an equimolar amount of concentrated hydriodic acid in acetonitrile at room temperature to give the desired products.

  • A Mild Ni/Cu-Catalyzed Silylation via C<i>–</i>O Cleavage
    作者:Cayetana Zarate、Ruben Martin
    DOI:10.1021/ja412107b
    日期:2014.2.12
    A Ni/Cu-catalyzed silylation of unactivated C-O electrophiles derived from phenols or benzyl alcohols is described. This transformation is characterized by its wide scope and mild conditions, providing a direct access to synthetically versatile silylated compounds. The protocol allows for the coupling of C(sp(2))-O and even C(sp(3))-O bonds with similar efficiency.

    based on the cheap transition metal nickel for the asymmetric hydrogenation of challenging cyclic alkenyl sulfones, 3-substituted benzo[b]thiophene 1,1-dioxides, was first successfully developed. A series of hydrogenation products, chiral 2,3-dihydrobenzo[b]thiophene 1,1-dioxides, were obtained in high yields (95–99%) with excellent enantioselectivities (90–99% ee). According to the results of nonlinear
