  Facile Synthesis of Z-Alkenes via Uphill Catalysis

  摘要：

  Catalytic access to thermodynamically less stable Z-alkenes has recently received considerable attention. These approaches have relied upon kinetic control of the reaction to arrive at the thermodynamically less stable geometrical isomer. Herein, we present an orthogonal approach which proceeds via photochemically catalyzed isomerization of the thermodynamic E-alkene to the less stable Z-isomer which occurs via a photochemical pumping mechanism. We consider two potential mechanisms. Importantly, the reaction conditions are mild, tolerant, and operationally simple and will be easily implemented.

• C–N Bond Formation from Allylic Alcohols via Cooperative Nickel and Titanium Catalysis

  Amination of allylic alcohols is facilitated via cooperative catalysis. Catalytic Ti(O-i-Pr)4 is shown to dramatically increase the rate of nickel-catalyzed allylic amination, and mechanistic experiments confirm activation of the allylic alcohol by titanium. Aminations of primary and secondary allylic alcohols are demonstrated with a variety of amine nucleophiles. Diene-containing substrates also cyclize

  通过协同催化促进烯丙基醇的胺化。催化性Ti（O - Pr）4可以显着提高镍催化的烯丙基胺化的速率，并且机械实验证实钛可以活化烯丙基醇。用各种胺亲核试剂证明伯和仲烯丙基醇的胺化。含二烯的底物在胺化之前还会环化在烯丙基镍中间体上，生成碳环胺产物。此串联过程仅在我们的协同催化系统下才能实现。

  Experimental and theoretical mechanistic studies on the Cu(OTf)2-catalyzed hydroamination reaction of terminal allenes with secondary amines reveal that in situ generated cationic Cu(I) is the catalytically active species and explain the observed regio- and stereoselectivity for the unbranched E product. Insight into the structure of the relevant transition states allowed the generalization of this

  对末端异位烯与仲胺的Cu（OTf）2催化加氢胺化反应的实验和理论机理研究表明，原位生成的阳离子Cu（I）是催化活性物质，并解释了所观察到的对直链E产物的区域和立体选择性。对相关过渡态结构的洞察力使这种方法可以推广到前所未有的温和和耐官能团条件下的烯丙酰胺和N-烯丙基氨基甲酸酯。除电子作用外，酰胺氧的螯合作用也解释了这类底物的高固有反应性。

  This manuscript details the development of a palladium-catalyzed allylic amination that proceeds via decarboxylation of ­allylic carbamates. Both saturated and aromatic heterocycles undergo decarboxylative rearrangement in good yields. The mechanism of allylation of heteroaromatic amines involves the formation of π-allyl palladium complexes followed by decarboxylation of the ­carbamate. Finally, the heteroaromatic anion equivalent is allylated to provide allylic amines.

  gold(I) catalyst in toluene at 80 °C gave the corresponding allylic amines in good to moderate yields. To the best of our knowledge, this is the first example for carrying out the gold-catalyzed -intermolecular hydroamination with an aliphatic amine.

  (CDC)-based pincer ligand scaffold is reported, along with its application to site-selective Rh(I)-catalyzed intermolecular hydroamination of 1,3-dienes with aryl and alkyl amines. To the best of our knowledge, this is the first example of the use of a well-defined CDC complex as an efficient catalyst. Transformations proceed in the presence of 1.0-5.0 mol % Rh complex at 35-120 °C; allylic amines are obtained
