Reactions at the Alpha Carbon Atom

The position next to the ketone or aldehyde functional group is termed as alpha position and the reaction which occurs at alpha position is called alpha substitution reaction. In an alpha substitution reaction, the alpha proton atom is substituted by an electrophile by the formation of an enol intermediate or enolate ion intermediate. Most of the carbonyl compounds go through an alpha substitution reaction.

HO, но. Chrysanthemic acid Chrysanthemyl alcohol OH H20 TsO. DMSO Chrysanthemyl tosylate Artemesia alcohol Yomogi alcohol Chrysanthemic acid occurs as a mixture of esters in flowers of the chrysanthemum (pyrethrum) family. Reduction of chrysanthemic acid to its alcohol, followed by conversion of the alcohol to its tosylate, gives chrysanthemyl tosylate. Solvolysis of the tosylate gives a mixture of artemesia and yomogi alcohols. Draw curved arrows to show the movement of electrons in this step of the reaction mechanism.
