The Stetter reaction is a reaction used in organic chemistry to form carbon-carbon bonds through a 1,4-addition reaction utilizing a nucleophilic catalyst. While the related 1,2-addition reaction, the benzoin condensation, was known since the 1830s, the Stetter reaction was not reported until 1973 by Dr. … Zobacz więcej As the Stetter reaction is an example of umpolung chemistry, the aldehyde is converted from an electrophile to a nucleophile under the reaction conditions. This is accomplished by activation from some catalyst - … Zobacz więcej Several variations of the Stetter reaction have been developed since its discovery in 1973. In 2001, Murry et al reported a Stetter reaction of aromatic aldehydes onto acylimine derivatives to give α-amido ketone products. The acylimine acceptors were … Zobacz więcej • Baylis–Hillman reaction Zobacz więcej The Stetter reaction produces classically difficult to access 1,4-dicarbonyl compounds and related derivatives.
