Electrophilic amination of Grignard reagents has been accomplished by using O-sulfonyloximes as amination reagents. Benzophenone O-sulfonyloxime derivatives react with Grignard reagents on sp2 nitrogen, yielding primary amines by successive hydrolysis of the resulting N-alkylimines. Various cyclic imines are synthesized by Pd-catalyzed reaction from olefinic oxime derivatives. That is, treatmen...

A copper(I)-catalyzed, (diacetoxyiodo)benzene [PhI(OAc)2]-mediated ring-expansion/thiolactonization of a-oxo ketene dithioacetals was efficiently realized via azidation of the internal olefinic C@H bond with sodium azide under mild conditions. Sequential amination, ring-expansion rearrangement, and thiolactonization occurred to form aminated thiolactones in the presence of acetic anhydride as t...

We developed a novel (S)-L-phenylalanine derived-bidentate chiral diaminophosphine oxide (DIAPHOX) preligand (S,S(P))-9b, which was successfully applied to Pd-catalyzed asymmetric allylic alkylation and amination. Using the Pd-(S,S(P))-9b catalyst system, asymmetric allylic alkylation and amination proceeded very smoothly, affording the corresponding products in excellent yield with high enanti...

An operationally simple and concise synthesis of anilinoethanolamines, as NMDA NR2B receptor antagonist ifenprodil analogues, was developed via a copper-catalyzed amination of the corresponding bromoarene. Coupling was achieved with linear primary alkylamines, alpha,omega-diamines, hexanolamine and benzophenone imine, as well as with aqueous ammonia, in good yields using CuI and N,N-diethylsali...

Waste glycerol was converted to secondary amines in a one pot reaction, using Clostridium butyricum and catalytic hydrogen transfer-mediated amination.

We have developed a general strategy for the synthesis of 2,5-syn disubstituted pyrrolidines that is based on the multi-faceted reactivity of the sulfone moiety and a 5-endo-trig cyclisation. This methodology was applied to the synthesis of indolizidine alkaloid monomorine I. Two factors were key to the success of this endeavour; the first was the choice of nitrogen protecting group whilst the ...

This feature article provides an overview of the application of organic azides for the intermolecular amination of sp(3) and sp(2) C-H bonds. The catalytic activity of several metal complexes was reviewed underlining both synthetic and mechanistic aspects of the C-H amination. The majority of the aminated compounds reported in literature have been collected in this paper to provide a compendium...

PEI modified graphene oxide (GOPEI) is prepared by tandem MW amination–microfiltration and used for arsenic removal from water.
