A Novel Three-Component Reaction toward Dihydrooxazolopyridines

Organic Letters, 2008
Isocyano 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 ...

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)]

Three-Component Reactions for Post-Polymerization Modifications

ACS Macro Letters, 2013
A 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.

Amino-Sulfonation of Alkenes in a Three-Component Reaction

European Journal of Organic Chemistry, 2002
2-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.
