Xu, Lei;Liu, Fu-Yue;Zhang, Qi;Chang, Wei-Jun;Liu, Zhong-Lin;Lv, Ying;Yu, Hai-Zhu;Xu, Jun;Dai, Jian-Jun;Xu, Hua-Jian research published 《 The amine-catalysed Suzuki-Miyaura-type coupling of aryl halides and arylboronic acids》, the research content is summarized as follows. A robust and chemoselective organocatalytic Suzuki-Miyaura-type coupling of aryl halides viz. Me 2-(4-bromophenyl)propanoate, Me 2-(4-chlorophenyl)propanoate, 5-bromopyrimidine, etc. with arylboronic acids viz. phenylboronic acid, naphthalen-2-ylboronic acid, furan-3-ylboronic acid, etc. catalyzed by amines, e.g. 2-methyl-N1,N3-di-o-tolylbenzene-1,3-diamine was reported. The utility and scope of this reaction were demonstrated by the synthesis of several com. relevant small mols. viz. Me 2-([1,1′-biphenyl]-4-yl)propanoate, Me 2-(4-(naphthalen-2-yl) phenyl)propanoate, 5-(furan-3-yl)pyrimidine, etc. and a selection of derivatives of pharmaceutical drugs e.g., Boscalid.
4595-59-9, 5-Bromopyrimidine is a reactive intermediate that is used in the synthesis of 4-methoxyphenylboronic acid. 5-Bromopyrimidine has been shown to be nucleophilic, reacting with β-amino acids under basic conditions to form the corresponding 2-bromo amide. It also undergoes cross-coupling reactions with halides and can be used as a building block for other organic compounds. 5-Bromopyrimidine has optical properties that are characteristic of aromatic molecules, including strong absorption bands in the ultraviolet region and visible light region.
5-Bromopyrimidine undergoes direct metallation with lithuium diisopropylamide to yield 4-lithio-5-bromopyrimidine., Application In Synthesis of 4595-59-9
