In 1887, chemist Sir Arthur Michael reported a nucleophilic addition reaction to the β-position of α,β- unsaturated carbonyl compounds. These reactions, named Michael addition reactions, have been extensively studied to date. In contrast, the anti-Michael addition reaction, referring to the nucleophilic addition reaction to the α-position, has been difficult to achieve. This is due to the higher electrophilicity of the β-position compared to the α-position.
