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, 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 ...
