Selective synthesis of benzo[4,5]imidazo[2,1-a]isoquinolines via copper-catalyzed tandem annulation of alkynylbenzonitriles with 2-Iodoanilines
Liu, Xiaodong,Deng, Guobo,Liang, Yun
, p. 2844 - 2847 (2018/06/18)
An efficient copper-catalyzed cascade cyclization reaction for selectively synthesizing a variety of benzo[4,5]imidazo[2,1-a]isoquinoline derivatives has been developed. The reaction features the formation of three different C–N bonds in sequence. In the
Rapid synthesis and zebrafish evaluation of a phenanthridine-based small molecule library
Donaldson, Lauren R.,Wallace, Stephen,Haigh, David,Patton, E. Elizabeth,Hulme, Alison N.
supporting information; experimental part, p. 2233 - 2239 (2011/04/27)
A Heck cyclisation approach is described for the rapid synthesis of a library of natural product-like small molecules, based on the phenanthridine core. The synthesis of a range of substituted benzylamine building blocks and their incorporation into the library is reported, together with a highly selective cis-dihydroxylation protocol that enables access to the target compounds in an efficient manner. Biological evaluation of the library using zebrafish phenotyping has led to the discovery of compound 20c, a novel inhibitor of early-stage zebrafish embryo development.
Palladium-Catalyzed Ring-Forming Aminoalkenylation of Alkenes with Aldehydes Initiated by Intramolecular Aminopalladation
Hu, Yue,Xie, Yinjun,Shen, Zhiqiang,Huang, Hanmin
supporting information, p. 2473 - 2477 (2017/02/23)
A palladium-catalyzed aminopalladation reaction followed by nucleophilic addition with aldehydes and dehydration is described. This direct and operationally simple procedure provides a rapid and reliable approach to a wide range of functionalized tetrahydroisoquinolines with high selectivity. Mechanistic studies disclosed that the nucleophilic addition, performed via a highly ordered transition-state, is the turnover-limiting step in which the inherent β-hydride elimination of the key Csp3?Pd species was controlled by the confined conformation and the nucleophilicity of the Csp3?Pd bond was enhanced by the strong electron-donating effect of the nitrogen atom.
Palladium-catalyzed highly selective ortho-halogenation (I, Br, Cl) of arylnitriles via sp2 C-H bond activation using cyano as directing group
Du, Bingnan,Jiang, Xiaoqing,Sun, Peipei
, p. 2786 - 2791 (2013/04/24)
A palladium-catalyzed ortho-halogenation (I, Br, Cl) of arylnitrile is described. The optimal reaction conditions were identified after examining various factors such as catalyst, additive, solvent, and reaction temperature. Using cyano as the directing group, the halogenation reaction gave good to excellent yields. The method is compatible to the arylnitriles with either electron-withdrawing or electron-donating groups. The reaction is available to the substrate in at least gram scale. The present method was successfully applied to the synthesis of the precursors of paucifloral F and isopaucifloral F.
A radical cyclization cascade of 2-alkynylbenzonitriles with sodium arylsulfinates
Zhou, Bang,Chen, Wenqi,Yang, Yuzhong,Yang, Yuan,Deng, Guobo,Liang, Yun
, p. 7959 - 7963 (2018/11/21)
A convenient radical cyclization cascade procedure for the construction of sulfonated indenones from 2-alkynylbenzonitriles and sodium arylsulfinates has been explored under mild reaction conditions. The present methodology offers a low-cost and operationally straightforward approach to synthesizing various sulfonated indenones in moderate to good yields by simple use of cheap sodium persulfate as an oxidant and environmentally benign water as a co-solvent.
