The synthetic utility of quinone imine ketals in the context of asymmetriccatalysis was disclosed for the first time. By expanding the utility of chiral Brønsted acid catalysis to the electrophilic activation of quinone imine ketals, we succeeded in the development of highly enantioselective arylation of encarbamates to give α-amino-β-aryl ethers wherein quinone imine ketals act as functionalized aromatic

general atom economic method for the isomerization of a broad range of N-allyl amides to form Z-di-, tri-, and tetrasubstituted enamides with exceptional geometric selectivity. This report represents the first examples of a catalytic isomerization of N-allyl amides to form nonpropenyl disubstituted, tri- and tetrasubstituted enamides with excellent geometric control. Applications of these geometrically

We present the first enantioselective catalysis of the Friedel−Crafts reaction via activation of electron-rich multiple bonds by a chiral Bronsted acid. The reaction of various indole derivatives with a broad range of substituted enecarbamates affords the corresponding Friedel−Crafts products in high yield and enantioselectivity.
A single-component, air-stable nickel precatalyst can catalyze the isomerization of allylamides for the synthesis of enamides. The scope of the reaction encompasses various substituted allylamides and allylcarbamates as well as homoallylamides. The reaction can be performed on a multigram-scale without specialized glove-box equipment or Schlenk techniques.
of a carbon–carbon double bond of N-allyl and N-homoallyl amides is described. While the transposition of acyclic amides gave very high Z-selectivity of the enamides, corresponding cyclic N-allyl amides led exclusively to the E-configured products. Thereby, we realised a stereodivergent approach to enamides that is dependent on the structure of the amide substituents. When homoallylic substrates are
