  • Fe-Catalyzed Multicomponent Reactions: The Regioselective Alkoxy Allylation of Activated Olefins and its Application in Sequential Fe Catalysis
    作者:André P. Dieskau、Michael S. Holzwarth、Bernd Plietker
    DOI:10.1002/chem.201103009
    日期:2012.2.20
    broadly applicable Fe‐catalyzed regioselective alkoxy allylation of activated double bonds. Substituted allylic carbonates are converted into the corresponding σ‐enyl Fe complexes by reaction with Bu4N[Fe(CO)3(NO)] (TBAFe) at 30 °C. The liberated alkoxide adds to an activated double bond with the generation of a C‐nucleophile, which is trapped by the σ‐enyl Fe complex in a regioselective manner. Alternatively
    我们在此介绍了一种多功能且广泛适用的活化双键的催化的区域选择性烷氧基烯丙基化反应。取代的烯丙基碳酸酯通过与Bu 4 N [Fe(CO)3(NO)](TBAFe)在30°C下反应转化为相应的σ-烯基Fe络合物。释放的醇盐会生成C-亲核试剂,从而形成一个活化的双键,该C-亲核试剂会以区域选择性的方式被σ-烯基Fe络合物捕获。或者,该醇盐在使经历迈克尔加成的外部前亲核试剂去质子化中用作碱。该方法的特点是宽泛的官能团耐受性,温和的反应条件,较低的催化剂载量和较高的区域选择性,有利于ipso取代产物。

    Iridium-catalyzed aminations of allylic carbonates containing a variety of O-functional groups have been explored. High degrees of regio- as well as enantioselectivity were achieved with diacylamides under salt-free conditions and with arylamines. The results allowed the antiepilepsy drug (S)-vigabatrin to be prepared via a very short route.

    developed. Mechanistic studies of the allylic vinylation reaction have been carried out, and the results suggest that the leaving group of the allylic precursor plays a key role in directing the reaction pathway. Screening of various allylic precursors showed that Ir-catalyzed reactions of allyl diethyl phosphates with o-aminostyrene derivatives proceed via an allylic amination pathway. A subsequent ring-closing
