Enantioselective 1,3-Dipolar Cycloaddition Reactions of C -Carboxy Ketonitrones and Enals with MacMillan Catalysts: Evidence of a Nonconcerted Mechanism

Autor: Souhir Abid, Arnaud Martel, Mathieu Y. Laurent, Gilles Dujardin, Khalid B. Selim, Kawther Ben Ayed

Publikováno v: European Journal of Organic Chemistry. 2017:6763-6774

Highly diastereo- and enantioselective 1,3-dipolar cycloadditions between functional ketonitrones and β-substituted enals are promoted by organocatalysis with the imidazolidinium catalyst of MacMillan. Study of the scope of the reaction shows that h

Publikováno v: Tetrahedron Letters. 57:5825-5829

Copper-catalyzed vinylation of 2- and 4-hydroxy pyridine and quinoline affords exclusively N-vinylation products. However, vinyl ethers of 4-hydroxy pyridine and quinoline can be prepared via a three-step sequence involving copper-catalyzed C-O cross
