Rhodium-Catalyzed Asymmetric Allylation of Malononitriles as Masked Acyl Cyanide with Allenes: Efficient Access to beta,gamma-Unsaturated Carbonyls
A rhodium-catalyzed regio- and enantioselective intermolecular allylation of malononitriles as masked acyl cyanides (MAC) with terminal and symmetrical internal allenes is reported. A RhI/Josiphos catalytic system combined with subsequent oxidative degradation of the primary adducts enables a straightforward access to alpha-branched, beta,gamma-unsaturated carbonyl compounds. The present protocol exhibits perfect atom economy in the allylation step and is characterized by a great functional group compatibility. Furthermore, the use of alpha-substituted malononitriles allowed for the construction of all-carbon quaternary centers.
