Abstract: The method relates to the field of asymmetric allylic amination and comprises preparing a chiral N-substituted allylic amine compound from the corresponding allylic substrates and substituted hydroxylamines, in the presence of a catalyst, said catalyst comprising copper compounds and a chiral ligand. Examples of chiral amine compounds which can be made using the method include Vigabatrin, Ezetimibe Terbinafine, Naftifine 3-methylmorphine, Sertraline, Cinacalcet, Mefloquine hydrochloride, and Rivastigmine. There are over 20,000 known bioactive molecules with chiral N-substituted allylic amine substructure. The method may also be used to produce non-natural chiral ß-aminoacid esters, a sub-class of chiral N-substituted allylic amine compounds. Examples of ß-aminoacid ester which can be produced by the disclosed method, include, but are not limited to, N-(2-methylpent-1-en-3-yl)benzenamine and Ethyl 2-methylene-3-(phenylamino)butanoate. Further, the products of the method described herein can be used to produce chiral heterocycles and bioactive molecules or materials. A novel chiral copper-BINAM nitrosoarene complex is also set forth.

Abstract: A catalyst comprising a NCN pincer ligand group VI complex is capable of being used as an olefin polymerization or isomerization catalyst that does not require an expensive cocatalyst. The complex has the NCN pincer ligand in a trianionic form with the group VI in the +3 oxidation state or the +4 oxidation state and complexed to an anionic hydrocarbon group, or the complex has the NCN pincer ligand in a dianionic form with the group VI in the +2 oxidation state. The complex is capable of initiating the polymerization of alkenes without an added activator. The presence of a water scavenger and activator or cocatalyst, such as triisobutylaluminum, increases the catalytic activity. The complex is capable of selectively isomerizing 1-alkenes to cis/trans 2-alkenes.
