  Mild-Condition Synthesis of Allenes from Alkynes and Aldehydes Mediated by Tetrahydroisoquinoline (THIQ)

  摘要：

  A practical 1,2,3,4-tetrahydroisoquinoline (THIQ)-mediated synthesis of 1,3-disubstituted allenes from terminal alkynes and aldehydes under mild conditions in the presence of CuBr first and then ZnI2 was reported. This telescoped allene synthesis reaction includes three consecutive steps and two reactions: first, a room-temperature CuBr-catalyzed synthesis of propargylamines, exo-yne-THIQs, from terminal alkynes, aldehydes, and THIQ then filtration of the CuBr catalyst, and finally the ZnI2-mediated allene synthesis from the generated exo-yne-THIQs under mild conditions (either at room temperature or heating at 50 or 75 degrees C). A wide range of aliphatic or aromatic aldehydes and terminal alkynes are tolerated, affording the allene products in up to 92% yield. Especially, temperature-sensitive aldehydes can be used in the reaction system. Preliminary exploration of the asymmetric allene synthesis has also been conducted, and a moderate enantioselectivity has been achieved. Finally, the relative reactivities of several secondary amines were compared with THIQ, showing that THIQ is the best of these amines in the synthesis of allenes under mild reaction conditions.

  An efficient and general protocol for the palladium-catalyzed Heck alkynylation of benzyl chlorides was developed. A catalyst system comprised of PdCl 2 (CH 3 CN) 2 and 2-dicyclohexyl-phosphino-2',4',6'-triisopropylbiphenyl (XPhos), with CS 2 CO 3 as the base, efficiently couples a wide range of functionalized terminal alkynes and substituted benzyl chlorides at 65 °C. We have also demonstrated that

  The indene moiety is an important unit because of its presence in many chemical catalysts, functional materials and biologically relevant molecules. Herein, we report a facile reaction of arylallenes with benzylic or allylic alcohols through TfOH/Fe(OTf)3 cocatalyzed cleavage of sp3 carbon‐oxygen. In the presence of 5 mol% TfOH and 5 mol% Fe(OTf)3, a range of arylallenes undergo carbocation initiated

  茚部分是重要的单元，因为它存在于许多化学催化剂，功能材料和生物学相关的分子中。在本文中，我们报道了通过TfOH / Fe（OTf）3共同催化的sp 3碳氧裂解，芳基烯与苄醇或烯丙基醇的反应很容易。在5mol％的TfOH和5mol％的Fe（OTf）3的存在下，一定范围的芳基亚芳基与烷基醇进行碳正离子引发的环化反应，从而以优异的产率获得结构多样的多取代的茚基。H 2 O是使这种转变具有高度原子经济性和环境友好性的唯一副产物。
