  • The MARDi Cascade: A Michael-Initiated Domino-Multicomponent Approach for the Stereoselective Synthesis of Seven-Membered Rings
    作者:Yoann Coquerel、Marie-Hélène Filippini、David Bensa、Jean Rodriguez
    DOI:10.1002/chem.200701708
    日期:2008.3.27
    allows regio- and stereocontrolled access to a variety of functionalised and substituted seven-membered rings. The substitution array can be diastereoselectively modulated by appropriate choice of the reaction partners, and the reaction allows the control of up to five newly created stereocentres and a complete chiral induction in the case of an optically active ketone precursor. The high level of
    MARDi级联是最近发明的涉及1,3-二羰基衍生物的三组分迈克尔引发的缩合反应。它允许区域控制和立体声控制访问各种功能化和取代的七元环。取代阵列可通过的反应伙伴适当选择非对映选择性调制,并将该反应允许多达五个新创建的立体中心和一个完整的手性诱导中的光学活性前体酮的情况下的控制。观察到的非对映选择性的高水平归因于反应的总热力学控制。
  • A Practical Method for the Synthesis of 2-Alkynylpropenals
    作者:Charnsak Thongsornkleeb、Rick L. Danheiser
    DOI:10.1021/jo047869a
    日期:2005.3.1
    A general method for the preparation of 2-alkynyl acroleins is described beginning with vinyl iodide 5 and involving a combination of Sonogashira coupling and Dess-Martin oxidation. Critical to the success of this approach is the use of a special workup procedure for the oxidation step. The resultant enynals participate in a variety of addition reactions including aldol condensations and reactions with organolithium compounds.
  • The MARDi Cascade:  A New Base-Induced Five-Step Anionic Domino Reaction for the Stereoselective Preparation of Functionalized Cycloheptenes
    作者:Marie-Hélène Filippini、Jean Rodriguez
    DOI:10.1021/jo970196u
    日期:1997.5.1
  • Creating Quaternary Centers with High Exo Stereoselectivity Using Activated α-Alkynyl Dienophiles
    作者:Sun-Joon Min、Gavin O. Jones、K. N. Houk、Samuel J. Danishefsky
    DOI:10.1021/ja073528d
    日期:2007.8.1
    Ethynyl substituents were used to direct a highly exoselective creation of quaternary carbon centers in Diels-Alder cycloaddition reactions involving activated alpha-alkynyl dienophiles. The origins of electronic activation and the high stereoselectivities of these reactions were investigated by the B3LYP density functional method.
