Zhang, Shuai;Xiao, Jun-Zhao;Li, Yan-Bo;Shi, Chang-Yun;Yin, Liang research published 《 Copper(I)-Catalyzed Asymmetric Alkylation of Unsymmetrical Secondary Phosphines》, the research content is summarized as follows. A Cu(I)-catalyzed asym. alkylation of HPAr1Ar2 with alkyl halides is uncovered, which provides an array of P-stereogenic phosphines in generally high yield and enantioselectivity. The electrophilic alkyl halides enjoy a broad substrate scope, including allyl bromides, propargyl bromide, benzyl bromides, and alkyl iodides. Also, 11 unsym. diarylphosphines (HPAr1Ar2) serve as competent pronucleophiles. The present methodol. is also successfully applied to catalytic asym. double and triple alkylation, and the corresponding products were obtained in moderate diastereo- and excellent enantioselectivities. Some 31P NMR experiments indicate that bulky HPPhMes exhibits weak competitively coordinating ability to the Cu(I)-bisphosphine complex, and thus the presence of stoichiometric HPAr1Ar2 does not affect the enantioselectivity significantly. Therefore, the high enantioselectivity in this reaction is attributed to the high performance of the unique Cu(I)-(R,RP)-TANIAPHOS complex in asym. induction. Finally, one monophosphine and two bisphosphines prepared by the present reaction are employed as efficient chiral ligands to afford three structurally diversified Cu(I) complexes, which demonstrates the synthetic utility of the present methodol.

3-Bromobenzyl bromide is a molecule that has been synthesized and shown to have anticancer activity. It inhibits the activity of cancer cells by binding to amines in these cells and preventing the formation of hydrogen bonds between these molecules. 3-Bromobenzyl bromide has also been shown to selectively inhibit the activity of NS5B polymerase, an enzyme that is important in the replication of the hepatitis C virus. The synthetic nature of this molecule makes it an attractive target for analytical methods such as nuclear magnetic resonance spectroscopy. This molecule also shows significant cytotoxicity against cancer cell lines in vitro, as well as inducing tumor necrosis factor-alpha (TNF-α) production in lps-stimulated murine macrophages., 823-78-9.
