    Stereostructure and thermodynamic stability of atropisomers of ortho-substituted 2,2′-diaryl-1,1′-binaphthalenes
    摘要:
    A series of ortho-substituted 2,2 '-aryl-1,1 '-binaphthalenes were prepared via Negishi arylation of 2,2 '-diiodo-1,1 '-binaphthalene in good to high yields (65-95%) as an equilibrium mixtures of up to three atropisomers (unlike,unlike, like,unlike, and like,like). Thermodynamic stability parameters of the atropisomers were evaluated from VT NMR spectra by regression analysis. The DFT parameters calculated using CAM-B3LYP functional comprising solvent permittivity were, apart from the toluene solution, which was expected to interact with the aromatic solute, in qualitative agreement with the experimental values. In the case of the ditolyl derivative, the population of the atropisomers was confirmed by CD spectroscopy via comparison with the population-weighted averaged spectrum computed using the M06 functional. X-ray structure analyses of particular atropisomers of the dianisyl, dianilinyl, and dinaphthyl derivatives are also presented and discussed. (C) 2013 Elsevier Ltd. All rights reserved.

    enantioselective Negishi cross‐coupling reaction, and the first arylation of α‐halo esters with arylzinc halides, are disclosed. Employing a cobalt‐bisoxazoline catalyst, various α‐arylalkanoic esters were synthesized in excellent enantioselectivities and yields (up to 97 % ee and 98 % yield). A diverse range of functional groups, including ether, halide, thioether, silyl, amine, ester, acetal, amide, olefin

    日期:2003.4.1
    A highly regio- and stereoselective halohydroxylation of 1,2-allenyl sulfoxides with X(+) and water was developed. The reaction shows E-stereoselectivity. In the iodohydroxylation reaction, I(2) was used to introduce the iodine atom. For bromohalohydroxylation, CuBr(2), NBS, or Br(2) can be used. When using I(2), NBS, or Br(2), the addition of LiOAc.2H(2)O is necessary for high yields of the halohydroxylation

    Roles reversed: An efficient cobalt‐catalyzed electrophilic amination of arylzinc reagents has been achieved. A variety of functionalized arylzincs and N‐chloroamines were coupled under mild conditions (see scheme). Both secondary and tertiary arylamines were obtained in moderate to excellent yields.

    Symmetrical diaryl ketones were prepared by a cross-coupling reaction between aryl bromides and ethyl chloroformate. This new method, which uses a catalyst composed of CoBr2 and a bipyridine ligand along with readily available starting materials, allows for the synthesis of a variety of symmetrical diaryl ketones in moderate to excellent yields (37–99 %) under mild conditions. This reaction, in which

    作者:Céline Dorval、Elodie Dubois、Yann Bourne‐Branchu、Corinne Gosmini、Grégory Danoun
    DOI:10.1002/adsc.201801577
    日期:2019.4.16
    Herein, a cobalt‐catalysed Negishi‐type crosscoupling of amide derivatives is described. Apart from being the first example of cobalt‐catalysed Negishi‐type coupling of amides, the process described employs a unique, simple, and cheap catalytic system to perform both the organozinc formation and the Negishi‐type coupling. Indeed, the same cobalt(II) bromide salt used to form the arylzinc species from
    本文描述了钴衍生物酰胺衍生物的Negishi型交叉偶联。除了作为钴钴酰胺的Negishi型偶联的第一个例子外,上述方法还采用了独特,简单且便宜的催化体系来进行有机锌的形成和Negishi型偶联。的确,然后在室温下重复使用了用于从芳基溴形成芳基锌物种的相同的溴化钴(II)盐,以实现该芳基锌与N-苯甲酰基戊二酰亚胺的交叉偶联。所呈现的反应的主要优点是其坚固性和易用性。确实,有机锌形成和Negishi型偶联反应是在没有对水或氧气采取预防措施的情况下进行的。
