  Regio- and Stereoselective Synthesis of Fluoroalkenes by Directed Au(I) Catalysis

  摘要：

  Au-catalyzed hydrofluorination reactions of a range of functionalized alkynes are reported. In the presence of an appropriate directing group, localized with particular spacing from the pendant alkyne, regioselective and predictable conversion of the alkyne to the Z-vinyl fluoride may be achieved, In selected cases, yields and selectivities are excellent. Additional experiments with two directing groups installed have established some initial principles with respect to a hierarchy of directing groups and their capacity for influencing hydrofluorination regioselectivity.

  A general and efficient protocol was developed for the synthesis of polysubstituted pyridines from propargyl amines and unsaturated carbonyl compounds through a tandem condensation/alkyne isomerization/6π 3‐azatriene electrocyclization sequence. This process was found to be applicable to a wide range of readily available substrates (30 examples, up to 95 % yield) and could be readily performed on a

  通过串联缩合/炔烃异构化/6π3-氮杂三烯电环化序列，从炔丙基胺和不饱和羰基化合物合成多取代吡啶的通用有效方法已被开发出来。发现该方法适用于广泛的容易获得的底物（30个实例，产率高达95％），并且可以容易地以制备性（20g）规模进行。通过利用该方法后期掺入吡啶，我们成功地完成了suveoline，norsuveoline和macrophylline的集体全合成。

  different methodologies have been developed for the synthesis of these kinds of molecules. However, a sustainable and efficient procedure for the synthesis of pyridines is still highly desirable. In this Synpacts article, we highlight our recent approach to the construction of highly substituted pyridines though a tandem condensation/alkyne isomerization/6π-3-azatriene electrocyclization sequence.

  吡啶是天然产物、药物和先进材料中普遍存在的结构杂环基序。已经开发了几种不同的方法来合成这些种类的分子。然而，仍然非常需要一种可持续且有效的吡啶合成方法。在这篇 Synpacts 文章中，我们重点介绍了我们最近通过串联缩合/炔烃异构化/6π-3-氮杂三烯电环化序列构建高度取代吡啶的方法。本协议用于合成一系列多取代吡啶 (30 个例子), 收率中等至良好。该过程还允许为 suaveoline、norsuaveoline 和 macrophylline 的集体全合成制定简明的策略。

  The non-enzymatic kinetic resolution of diversely substituted primary propargylic amines is reported featuring a highly selective acetyl transfer using (1S,2S)-1 in conjunction with AliquatTM 336, affording the corresponding enantio-enriched N-acetylated propargylic amines with unprecedented levels of selectivity (s-factors of up to 193 at 50% conversion).

  An efficient kinetic resolution of primary propargylic amines with s-factors of up to 56 is reported. The strategy is based on a dual catalytic approach, namely the use of a newly developed and easy-to-make thiourea-amide anion binding catalyst in combination with 4-(dimethylamino)pyridine (DMAP), both employed at a 5 mol% catalyst loading. Benzylic amines are also resolved with s-factors of up to 38.
