Copper-Catalyzed Remote C(sp3)-H Phosphorothiolation of Sulfonamides and Carboxamides in a Multicomponent Reaction.

Organic Letters, 2020
The catalytic C(sp3)-H functionalization is highly desirable yet challenging in organic synthesis. Incorporation of the SP(O)(OR)2 group through C(sp3)-H functionalization remains unexplored.

Synthesis of (E)-Quinoxalinone Oximes through a Multicomponent Reaction under Mild Conditions.

Organic Letters, 2020
Herein, a novel method for the gram-scale synthesis of (E)-quinoxalinone oximes through a multicomponent reaction under mild conditions is described. Such a transformation was performed under transition-metal-free conditions, affording (E)-oximes in a ...

Photoinduced Multicomponent Reactions

Angewandte Chemie International Edition, 2016
AbstractThe combination of multicomponent approaches with light‐driven processes opens up new scenarios in the area of synthetic organic chemistry, where the need for sustainable, atom‐ and energy‐efficient reactions is increasingly urgent. Photoinduced multicomponent reactions are still in their infancy, but significant developments in this area are ...

The Gewald multicomponent reaction

Molecular Diversity, 2010
The Gewald reaction of sulfur, cyanoacetic acid derivatives, and oxo-component (G-3CR) yielding highly substituted 2-aminothiophene derivatives has seen diverse applications in combinatorial and medicinal chemistry. Its products are of great use in pharmaceutical industry mainly as small molecular weight inhibitors. We herein review synthetic scope and

Multicomponent Reactions of Cyclobutanones

The Journal of Organic Chemistry, 2009
Cyclobutanones are essentially unknown as reactants in isonitrile-based multicomponent reactions. Ugi reactions of cyclobutanone and Passerini reactions of tetramethylcyclobutane-1,3-dione have been performed in this work. These reactions are significantly enhanced by being conducted in water, a subject of recent interest whose basis is still in ...
