    摘要:
    B(C6F5)(3) as a catalyst and polymethylhydrosiloxane as a hydride source have been employed for the reductive dehydroxylation of Baylis-Hillman adducts wherein the hydride adds in an S(N)2' manner onto the unactivated allyl alcohol moiety with concomitant elimination of the hydroxy group along with double bond migration. The products formed were found to be E in the case of ester adducts and Z in the case of nitrile adducts. (c) 2006 Elsevier Ltd. All rights reserved.

  • An Organocatalytic Asymmetric Nazarov Cyclization
    作者:Ashok K. Basak、Naoyuki Shimada、William F. Bow、David A. Vicic、Marcus A. Tius
    DOI:10.1021/ja103028r
    日期:2010.6.23
    An organocatalytic asymmetric Nazarov cyclization of diketoesters that proceeds by means of a dual activation mechanism has been developed. Screening of a number of catalysts led to a new thiourea that incorporates a primary amino group. The method gives rise to cyclic products with two adjacent quaternary asymmetric carbon atoms, one of which is an all-carbon stereocenter, with complete or nearly
    已经开发了通过双重活化机制进行的二酮酯的有机催化不对称 Nazarov 环化。对许多催化剂的筛选产生了一种新的硫脲,它包含一个伯氨基。该方法产生具有两个相邻季不对称碳原子的环状产物,其中一个是全碳立体中心,具有完全或几乎完全的非对映选择性和高或非常高的对映体过量。还描述了通过亲核加成到乙烯酮的无环二酮酯起始材料的简单且非常方便的合成。
  • An Efficient and General Method for the Heck and Buchwald–Hartwig Coupling Reactions of Aryl Chlorides
    作者:Dong-Hwan Lee、Abu Taher、Shahin Hossain、Myung-Jong Jin
    DOI:10.1021/ol202177k
    日期:2011.10.21
    The β-diketiminatophosphane Pd complex acted as a powerful catalyst for the Heck coupling of aryl chlorides with alkenes. Various aryl and heteroaryl chlorides were coupled efficiently under relatively mild conditions. Furthermore, this catalytic system also proved to be highly active in the Buchwald–Hartwig coupling of deactivated and sterically hindered aryl chlorides at room temperature.
    β-二酮基亚氨基膦Pd络合物可作为芳基氯化物与烯烃的Heck偶联的有力催化剂。在相对温和的条件下有效地偶联了各种芳基和杂芳基氯化物。此外,在室温下,这种催化体系在失活的和位阻的芳基氯化物的布赫瓦尔德-哈特维格偶联中也被证明具有很高的活性。
  • Neutral Nazarov-Type Cyclization Catalyzed by Palladium(0)
    作者:Naoyuki Shimada、Craig Stewart、William F. Bow、Anais Jolit、Kahoano Wong、Zhe Zhou、Marcus A. Tius
    DOI:10.1002/anie.201201724
    日期:2012.6.4
    Joining the circle: The first Pd0 catalyzed Nazarov‐type cyclization of diketoesters (see scheme) proceeds in 70 % to 95 % yield under strictly neutral pH conditions. Aryl substitution of the diketoesters is not required, so the reaction shows great versatility and can also proceed with aliphatic substrates.
    加入循环: 在严格中性 pH 条件下,第一个 Pd 0催化的 Nazarov 型二酮酯环化(见方案)以 70% 至 95% 的产率进行。不需要二酮酯的芳基取代,因此该反应显示出很大的通用性,也可以用脂肪族底物进行。

    作者:Thibaud Brégent、Jean-Philippe Bouillon、Thomas Poisson

    日期:2020.10.2
    The contra-thermodynamic isomerization of α- and β-substituted cinnamate derivatives catalyzed by the Cu(OAc)2/rac-BINAP complex under blue light irradiation is reported. The use of an oxazolidinone template, which favored the complexation of the copper catalyst to the substrate, allowed the E → Z isomerization of the catalytically formed chromophore under simple and robust reaction conditions in good
