    spirocyclopropanation/Cloke-Wilson rearrangement reactions have been developed to synthesize γ-butyrolactones using alkylidene Meldrum's acids and benzyl halides. The DBU-promoted spirocyclopropanation was carried out efficiently at room temperature to generate trans-isomeric spirocyclopropyl Meldrum's acid, and the following stereospecific thermal decarboxylative Cloke-Wilson rearrangement afforded trans-γ-butyrolactones

    作者:H.M. Walborsky、M. Topolski

    Substituted cyclopropyl ether 3 is readily available from γ-bromoalkylidene malonate 2 via a Michael Induced Ring Closure (MIRC) reaction with sodium methoxide. Single Electron Transfer mechanism is suggested for the key cyclization step to account for the observed high reactivity of a tertiary halide, phosphonium salt and nitro compound.

    We document a copper-catalyzed, enantioselective, conjugate addition involving the direct use of a terminal acetylene, which undergoes in situ metalation. The addition reactions of phenylacetylene to Meldrum's acid derived acceptors take place in aqueous media, without recourse to inert atmosphere. The success of the enantioselective process was enabled by the use of a new class of conveniently accessed
    我们记录了铜催化的对映选择性共轭加成,涉及直接使用末端乙炔,该乙炔进行原位金属化。苯乙炔与 Meldrum 酸衍生受体的加成反应在水性介质中进行,无需借助惰性气氛。对映选择性过程的成功是通过使用一类新的方便访问的 P,N 配体,我们称之为 PINAP 实现的。这些模块化配体对允许优化反应的许多电子和空间修饰有响应。
