  • Tridentate Nickel(II)-Catalyzed Chemodivergent C–H Functionalization and Cyclopropanation: Regioselective and Diastereoselective Access to Substituted Aromatic Heterocycles
    作者:Ekta Nag、Sai Manoj N. V. T. Gorantla、Selvakumar Arumugam、Aditya Kulkarni、Kartik Chandra Mondal、Sudipta Roy
    DOI:10.1021/acs.orglett.0c02138
    日期:2020.8.21
    Schiff-base nickel(II)-phosphene-catalyzed chemodivergent C–H functionalization and cyclopropanation of aromatic heterocycles is reported in moderate to excellent yields and very good regioselectivity and diastereoselectivity. The weak, noncovalent interaction between the phosphene ligand and Ni center facilitates the ligand dissociation, generating the electronically and coordinatively unsaturated active
    据报道,席夫碱镍(II)-膦催化的化学发散C–H官能团和芳族杂环的环丙烷化具有中等至极好的收率,以及非常好的区域选择性和非对映选择性。ligand配体与Ni中心之间的弱,非共价相互作用促进了配体的离解,从而生成了电子和配位不饱和活性催化剂。所报导的反应机理与实验结果和理论计算结果吻合良好,为环丙烷化反应提供了合适的立体控制模型。
  • Azabicyclo[3.2.0]heptan-7-ones (carbapenams) from pyrrole
    作者:Thomas L. Gilchrist、Américo Lemos、Carol J. Ottaway
    DOI:10.1039/a703170j
    日期:——
    The azabicyclo[3.2.0]heptan-7-ones 4, 10, 16 and 24 have been prepared from pyrrole. The same general approach has been used for all these derivatives; namely, substitution of pyrrole at the 2- and 5-carbon atoms, catalytic hydrogenation to produce pyrrolidine-2-acetic acid derivatives, and cyclisation using tris(1,3-dihydro-2-oxobenzoxazol-3-yl)phosphine oxide 6. The catalytic hydrogenation of 2,5-disubstituted pyrroles gives only the corresponding cis-2,5-disubstituted pyrrolidines. The hydrogenation proceeds more easily when the nitrogen atom bears a tert-butoxycarbonyl substituent. The N-tert-butoxycarbonylpyrroles 8 and 21 bearing an α-substituent in the acetate side chain were hydrogenated with a high degree of facial stereoselectivity. This allowed the 6-phthalimidoazabicyclo[3.2.0]heptan-7-one 24 to be isolated as a single diastereoisomer. The X-ray crystal structure of a precursor, the triester, 22a, has been obtained.
    由吡咯制备出氮杂双环[3.2.0]庚烷-7-酮 4、10、16 和 24。所有这些衍生物都采用了相同的一般方法,即在 2 碳原子和 5 碳原子上取代吡咯,催化加氢生成吡咯烷-2-乙酸衍生物,并使用三(1,3-二氢-2-氧代苯并恶唑-3-基)氧化膦 6 进行环化。2,5-二取代吡咯的催化氢化反应只能得到相应的顺式-2,5-二取代吡咯烷。当氮原子带有叔丁氧羰基取代基时,氢化反应更容易进行。醋酸侧链上带有 α 取代基的 N-叔丁氧羰基吡咯 8 和 21 在氢化过程中具有很高的面立体选择性。这使得 6-邻苯二甲酰亚胺基氮杂双环[3.2.0]庚烷-7-酮 24 以单一非对映异构体的形式分离出来。前体三酯 22a 的 X 射线晶体结构已经获得。
  • Formal total synthesis of (±)-rhazinal and its B-ring carbamate analogue
    作者:Munnuri Sailu、Swapnil S. Muley、Amitava Das、Prathama S. Mainkar、Srivari Chandrasekhar
    DOI:10.1016/j.tet.2014.12.090
    日期:2015.2
    Rhazinal and its analogues are microtubule and tubulin polymerisation disrupting agents. A formal synthesis of rhazinal is described. An interesting observation from the studies emerged about reposition of the natural product with slight modification in the structure. This opens up new possibilities for older natural products for finding better therapeutics. B-ring carbamate of rhazinal showed AChE inhibitory activity comparable to known reference standard galantamine and no cytotoxicity. (C) 2014 Elsevier Ltd. All rights reserved.

    electron-rich aromatic compounds with diazo esters. C-2-alkylated indoles and pyrroles are obtained with good yields even though the photocatalyst loading is as low as 0.075 mol %. For EWG-substituted substrates, the addition of a catalytic amount of N,N-dimethyl-4-methoxyaniline is required. Both EWG-EWG- and EWG-EDG-substituted diazo esters are suitable as alkylating agents.
