Catalytic Enantioselective Passerini Three‐Component Reaction
Angewandte Chemie International Edition, 2007 A [(salen)-AlIIICl] complex catalyzes the Passerini three-component reaction of an aldehyde, a carboxylic acid, and an isocyanide to afford alpha -acyloxyamides, e.g., I, with good to excellent enantioselectivity. A variety of nonchelating substrates can be used to generate the versatile chiral products. [on SciFinder (R)]

A Novel Three-Component Reaction toward Dihydrooxazolopyridines
Organic Letters, 2008Isocyano dihydropyridones accessible via a recently reported multicomponent reaction react with aldehydes and amines to afford dihydrooxazolopyridines in high yield. The scope and limitations of this novel multicomponent reaction were investigated. The efficient combination of two highly variable multicomponent reactions allows the construction of a ...

Three-Component Reactions for Post-Polymerization Modifications
ACS Macro Letters, 2013A Cu-catalyzed multi-component reaction (CuMCR) of terminal alkynes, sulfonyl azides, and amines was employed in a post-polymerization modification process. The reaction was conducted on polystyrene bearing 20 mol % alkyne groups with 4-toluenesulfonyl azide and dihexylamine in the presence of a Cu(PPh3)3Br/diisopropylethylamine catalyst.

Three-Component Reactions of Halogenotrinitromethanes with Alkenes
Synthesis, 2005Three-component one-pot reactions of bromotrinitromethane with bicyclobutylidene and methylenecyclobutanes provide a simple route to halogen-substituted isoxazolidines of mixed composition. With these same olefins, iodotrinitromethane gives adducts which decomposed rapidly to yield the corresponding isoxazolines.

Amino-Sulfonation of Alkenes in a Three-Component Reaction
European Journal of Organic Chemistry, 20022-aminoalkanesulfonic acids were synthesized by a three-component alkene-SO3.DMF-acetonitrile reaction, followed by acetamido hydrolysis. Trifluoromethanesulfonic acid was added to the amino-sulfonation mixture to accelerate the reaction and prevent the competitive formation of by-products.

AUTOWAVES AND SOLITONS IN A THREE-COMPONENT REACTION–DIFFUSION SYSTEM
International Journal of Bifurcation and Chaos, 2002We study the propagation of nonlinear waves in a three-component reaction–diffusion system. The problem of the existence of the stationary pulse-like solutions is reduced to the analysis of homoclinic trajectories of a fourth-order system of nonlinear ODEs.
