Zhu, Bin-Bin;Ye, Wen-Bo;He, Zhi-Tao;Zhang, Shu-Sheng;Feng, Chen-Guo;Lin, Guo-Qiang research published 《 Regioselective Tandem C-H Alkylation/Coupling Reaction of ortho-Iodophenylethylenes via C,C-Pallada(II)cycles》, the research content is summarized as follows. Five-membered C,C-pallada(II)cycles are a unique class of diorganopalladium species with favorable stability and an electron-rich nature, leading to efficient sequential reactions with diverse electrophiles and nucleophiles. Specifically, the development of aryl-alkenyl-palladacycle-based transformations could provide an attractive approach with regio- and stereocontrol for the construction of multifunctionalized arylethylenes. However, currently, the C,C-pallada(II)cycle formation relies on a rigid skeleton or steric congestion in the backbone to promote cyclopalladation, and the formation of aryl-alkenyl-palladacycle without an α-substituent has not been achieved. Furthermore, reactions that could discriminate between the two sp2 carbon centers of such C(sp2),C(sp2)-palladacycle remain elusive. Herein, a regioselective three-component tandem alkylation/coupling reaction applicable for a variety of non-, α-, or β-substituted and α,β-disubstituted ortho-iodophenylethylenes is reported. Electron-rich 2-pyridone ligands are employed to enable the cyclopalladation process leading to aryl-alkenyl-palladacycle intermediates, of which the two C-Pd bonds are discriminated toward alkylation by their inherent steric and electronic differences. Good linear free-energy relationships between regio-/chemoselectivities and Hammett σ values are observed
4897-84-1, Methyl 4-bromobutyrate,also as known as 4-Bromobutyric acid methyl ester, is a useful research compound. Its molecular formula is C5H9BrO2 and its molecular weight is 181.03 g/mol. The purity is usually 95%.
4-Bromobutyric acid methyl ester is a synthetic compound that can be used to inhibit the activity of the G1 phase cyclin-dependent kinases. It has been shown to inhibit protein synthesis by alkylating the amino groups of proteins and fatty acids. 4-Bromobutyric acid methyl ester also inhibits the growth of cancer cell lines, such as renal carcinoma cells. The mechanism of action for this drug is not well understood, but it may be due to its ability to bind with monoclonal antibodies and enter kidney cells by passive diffusion., Formula: C5H9BrO2
