We have developed the Morita-Baylis-Hillman reaction to include, for the first time in a completely organomediated process, intramolecular examples bearing allylic leaving groups as the electrophilic partner providing a facile, high yielding, straightforward synthesis of densely functionalized cyclic molecules.

Upon exposure of mono-enone mono-allylic carbonates to tributylphosphine and 1 mol % Pd(Ph3P)4, efficient conversion to the corresponding cycloallylated products is achieved. This transformation combines the nucleophilic features of the Morita-Baylis-Hillman reaction with the electrophilic features of the Trost-Tsuji reaction.
