Fujimoto-Belleau reaction
The Fujimoto-Belleau reaction is a name reaction in organic chemistry. It is named after the two chemists George I. Fujimoto and Bernard Belleau and is used for the synthesis of α-substituted α, β- enones .
Overview reaction
The reaction makes it possible, with the aid of a Grignard compound , to synthesize α-substituted α, β- enones from cyclic enol lactones .
Reaction mechanism
In the proposed reaction mechanism, the enol lactone reacts via various intermediate stages to form the α, β-enone:
