A copper(ii) acetate catalyzed ring-opening cross-coupling of cyclopropanol with sulfonyl azide has been developed. By this method, various β-amino ketones have been made efficiently in medium to high yields and venerable functional groups such as benzylic C-H, alkyl and aryl bromides, alkyl sulfonate, silyl ether and alkene are compatible with these reaction conditions. Control experiments have precluded the involvement of both radical and simple copper nitrene intermediates and a possible mechanism featuring key steps of ring-opening metalation and alkyl group migratory insertion into copper nitrene has been proposed.
Merging alkenyl C-H activation with the ring-opening of 1,2-oxazetidines: Ruthenium-catalyzed aminomethylation of enamides

1,2-Oxazetidines have been utilized as formaldimine precursors for the direct aminomethylation of enamides under a Ru(ii) species. By merging alkenyl C-H activation with ring-opening of 1,2-oxazetidines, this efficient protocol provides a facile and novel

Paragraph 0033; 0034-0036, (2017/08/24)
The invention discloses a preparation method of beta-aminoketone. According to the preparation method, aromatic ring substituted propargyl alcohol and amide are taken as raw materials, and tandem Meyer-Schuster rearrangement reaction and intermolecular amine hydrogenation addition reaction are performed by the action of acid, so that one-pot synthesis of beta-aminoketone is achieved. The maximum output of the preparation method of beta-aminoketone can reach 94%; the method has the advantages of simplicity in operation, 100% atom use ratio, economy and the like; and a novel synthesis method is provided for constructing beta-aminoketone compounds.
