An organocatalytic asymmetric allylic amination of Morita-Baylis-Hillman carbonates with aromatic amines in the presence of β-isocupreidine is described. Chiral allylic amines were obtained in almost quantitative yields (90-96%) with moderate enantioselectivity. Recrystallization afforded products in good yields (45-73%) and high optical purity (82-99% ee). This method provides a facile and efficient route to obtain optically active β-lactams, including the building block of the cholesterol-lowering drug Ezetimibe.
The orthopalladation of aniline via its 2-nitrophenylsulfenyl derivative

2-Nitrophenylsulfenylanilide can be orthopalladated to give μ,μ-dichlorodipalladium-bis(2-nitrophenylsulfenylanilide), which on carbometoxylation gives 2-nitrophenylsulfenylanthranylate.
