PALLADIUM(0) CATALYZED 3-AZA-COPE REARRANGEMENT OF N-ALLYLENAMINES

Pd(0) complexes catalyze the 3-Aza-Cope rearrangement of N-allylenamines to the corresponding δ,ε-unsaturated imines or γ,δ-unsaturated carbonyl compounds in the presence of trifluoroacetic acid as co-catalyst.

Counterion-Enhanced Pd/Enamine Catalysis: Direct Asymmetric α-Allylation of Aldehydes with Allylic Alcohols by Chiral Amines and Achiral or Racemic Phosphoric Acids

We report a straightforward and efficient Pd/enamine catalytic procedure for the direct asymmetric α-allylation of branched aldehydes. The use of simple chiral amines and easily prepared achiral or racemic phosphoric acids, together with a suitable Pd-source resulted in a highly active and enantioselective catalyst system for the allylation of various α-branched aldehydes with different allylic alcohols. The reported procedure could provide an easy access to both product antipodes. Furthermore, two possible orthogonal derivatizations of the enantioenriched aldehydes were performed without any decrease in enantioselectivity.

Palladium(0)-Catalyzed Rearrangement of N-Allylenamines. Synthesis of δ,ε-Unsaturated Imines and γ,δ-Unsaturated Carbonyl Compounds

Palladium-catalyzed rearrangement of N-allylenamines proceeds readily in the presence of a catalytic amount of trifluoroacetic acid to give δ,ε-unsaturated imines.Conveniently, δ,ε-unsaturated imines can be prepared directly by the reaction of allylamines with carbonyl compounds under the same conditions highly efficiently.The reaction involves oxidative addition of Pd(0) species to allylenammonium salts to give ?-allylpalladium complexes, which undergo intramolecular nucleophilic reaction with enamines give imines.The δ,ε-unsaturated imines are versatile synthetic precursors such as γ,δ-unsaturated carbonyl compounds.Synthetic applications are also described.
