Fujimoto-Belleau reaction
From Wikipedia, the free encyclopedia
The Fujimoto-Belleau reaction is a chemical reaction that forms cyclic α-substituted α,β-unsaturated ketones from enol lactones. The reaction is named after the two chmists George I. Fujimoto and Bernard Belleau.
The reaction is a Grignard reaction, followed by a H-shift and an Aldol addition reaction. The last step is an elimination (Aldol condensation) reaction with an E1CB mechanism.
