Allylation of carbonyl groups

Compared with the direct allylation of carbonyl groups, little has been reported on the selective conjugate allylation of enones. Allylic tantalum species, generated by the Sn-Ta exchange, is the choice of tools for performing conjugate addition of sterically hindered allylic groups (Equation (43)).140... [Pg.353]

The trimethylammonium iodide of 2-(dimethylaminomethyl)-3-(trimethylsilyhnethyl)-1,3-butadiene is a useful reagent for the introduction of both electrophile and nucleophile. Treatment with lithium enolate in the presence of Pd(PPh3)4 catalyst gives the allylated cyclopentanone, and subsequent intramolecular allylation of carbonyl group in the presence of B114NF gives vicinal exocyclic alcohol (Scheme 5). ... [Pg.185]

The metal-catalyzed allylation of carbonyl groups is a classical reaction in organic chemistry. However, the reverse reaction pathway, the retro-allylation, is... [Pg.175]
