A Practical Procedure for Regioselective Bromination of Anilines
Takahashi, Yusuke,Seki, Masahiko
, p. 1828 - 1832 (2021/04/15)
A highly practical procedure for the preparation of bromoanilines by using copper-catalyzed oxidative bromination has been developed. Treatment of free anilines with readily available NaBr and Na 2S 2O 8in the presence of a catalytic amount of CuSO 4·5H 2O enabled regioselective bromination.

METHOD FOR PRODUCING AROMATIC HALOGEN DERIVATIVE
-
Paragraph 0127-0131, (2020/07/28)
PROBLEM TO BE SOLVED: To provide a highly efficient and economically advantageous method for producing a halogen compound. SOLUTION: The method produces a halogen compound represented by formula (2) (X is a halogen atom, and b is an integer of 1-5) by reacting an aniline derivative represented by formula (1) (R1 is an ester group, a carbonyl group, a nitrile group, a nitro group, an optionally substituted alkyl group or an optionally substituted aralkyl group, and a is an integer of 0-4) with a halogenating agent in the presence of a copper catalyst and a persulfate.

One-Pot Synthesis and Conformational Analysis of Six-Membered Cyclic Iodonium Salts
Caspers, Lucien D.,Spils, Julian,Damrath, Mattis,Lork, Enno,Nachtsheim, Boris J.
, p. 9161 - 9178 (2020/08/14)
Two one-pot procedures for the construction of carbon-bridged diaryliodonium triflates and tetrafluoroborates are described. Strong Br?nsted acids enable the effective Friedel-Crafts alkylation with diversely substituted o-iodobenzyl alcohol derivatives, providing diphenylmethane scaffolds, which are subsequently oxidized and cyclized to the corresponding dibenzo[b,e]iodininium salts. Based on NMR investigations and density functional theory (DFT) calculations, we could verify the so-far-undescribed existence of two stable isomers in cyclic iodonium salts substituted with aliphatic side chains in the carbon bridge.
Scaffold Hopping of Natural Product Evodiamine: Discovery of a Novel Antitumor Scaffold with Excellent Potency against Colon Cancer
Wang, Lei,Fang, Kun,Cheng, Junfei,Li, Yu,Huang, Yahui,Chen, Shuqiang,Dong, Guoqiang,Wu, Shanchao,Sheng, Chunquan
, p. 696 - 713 (2020/02/04)
Inspired by the natural product evodiamine, a novel antitumor indolopyrazinoquinazolinone scaffold was designed by scaffold hopping. Structure-activity relationship studies led to the discovery of compound 15j, which shows low nanomolar inhibitory activity against the HCT116 cell line. Further antitumor mechanism studies indicated that compound 15j acted by the dual inhibition of topoisomerase 1 and tubulin and induced apoptosis with G2 cell-cycle arrest. The quaternary ammonium salt of compound 15j (compound 15js) exhibited excellent in vivo antitumor activity (TGI = 66.6%) in the HCT116 xenograft model with low toxicity. Indolopyrazinoquinazolinone derivatives represent promising multitargeting antitumor leads for the development of novel antitumor agents.
Cu-mediated selective bromination of aniline derivatives and preliminary mechanism study
Zhao, Hong-Yi,Yang, Xue-Yan,Lei, Hao,Xin, Minhang,Zhang, San-Qi
supporting information, p. 1406 - 1415 (2019/05/01)
A simple and efficient bromination of aniline, aniline derivatives, and analogs have been developed. Forty three examples were given and the highest yield reached was 98%. Different substrates including substituted aniline, pyridin-amine, N-substituted aniline, N,N-disubstituted aniline, N-phenyl-amide, N-phenyl-sulfonamide, and nitrogen-containing heterocycles were all reactive and selectively generated desired bromo-products. The method can be applied to synthesize drug intermediate and quinoxaline derivatives.
