Synthesis of 2,4,5-triarylated imidazoles via three-component domino reaction under catalyst-free conditions

Journal of Saudi Chemical Society, 2016
A one-pot synthesis of 2,4,5-triarylated imidazoles via three-component domino reaction of 2,2-dibromo-1,2-diarylethanones, ammonium acetate, and aryl aldehydes under catalyst-free conditions is developed. The scope of this reaction is studied.

Domino reactions of 2H-azirines with acylketenes from furan-2,3-diones: Competition between the formation of ortho-fused and bridged heterocyclic systems

Beilstein Journal of Organic Chemistry, 2014
3-Aryl-2H-azirines react with acylketenes, generated by thermolysis of 5-arylfuran-2,3-diones, to give bridged 5,7-dioxa-1-azabicyclo[4.4.1]undeca-3,8-diene-2,10-diones and/or ortho-fused 6,6a,12,12a-tetrahydrobis[1,3]oxazino[3,2-a:3′,2′-d]pyrazine-4,10 ...

Chiral Copper Catalysis in Enantioselective Domino Reactions. [PDF]

Molecules
This review updates the field of enantioselective copper-catalysed domino reactions promoted by chiral green copper catalysts, covering the literature since 2017. These complexes are derived from a diversity of chiral ligands, including mostly bisoxazolines and biphosphines along with monophosphines, N-heterocyclic carbenes, proline derivatives ...
