Abstract The conversion of C?H bonds to C?N offers a sustainable and economical strategy for the synthesis nitrogen-containing compounds. However, challenges regarding control regio- stereoselectivity currently limit broad applicability intermolecular C( sp 3 )?H amination reactions. We address these restrictions by directed nitrene-mediated insertion using metal-coordinating functional group. ...

Copper amine oxidases (CAOs) catalyse the oxidative de-amination of biogenic amines which are ubiquitous compounds essential for cell growth and proliferation. The enzymes are homodimers containing both topaquinone and a Cu(II) ions as cofactors at the active site of each subunit. After extraction and purification of chickpea (cicer arietinum) amine oxidase by chromatoghraphy, Km and Vmax of th...

A selective synthesis of 7- or 14-nitrogen containing tricyclic diterpenoids was completed according to a strategy in which the key step was the catalyzed direct allylic amination of methyl 14α-hydroxy-15,16-dihydroisopimarate with a wide variety of nitrogenated nucleophiles. It was revealed that the selectivity of the reaction depends on the nature of nucleophile. The catalyzed reaction of the...

Herein we have identified an optimal catalyst, Pd1Ag1.7, for the tandem reductive amination between nitroarenes and aldehydes (selectivity > 93%). Key to the success is the ability to control the compositions of the investigational Pd1-xAgx (x = 0-1) catalysts, as well as the clear composition dependent activity/selectivity trend observed in this study. This catalyst features a wide substrate s...

Fabricating crosslinked radiation-grafted anion-exchange membranes using a diamine in the amination synthesis step leads to better permselectivity-resistance balance compared use of divinylbenzene grafting step.

Процесс восстановительного аминирования лежит в основе полученная различных ценных химических веществ. Одним из важных классов таких химикатов являются N-содержащие функциональные соединения, которые можно применять качестве исходного материала или растворителя для синтеза фармацевтических препаратов и агрохимикатов. В последние годы было проведено множество исследований по поиску наиболее акти...
