An effective Pd(0)-catalyzed hydrocarboxylation of enimides with formicacid in the presence of a catalytic amount of HCOOPh is described. A variety of β-amino acid derivatives are obtained in good yields with high regioselectivities without using external toxic CO gas.

palladium-catalyzed intermolecular aminocarbonylation of alkenes has been developed in which the employment of hypervalent iodine reagent can accelerate the intermolecular aminopalladation, which thus provides the successful catalytic transformation. The current transformation presents one of the most convenient methods to generate β-amino acid derivatives from simple alkenes.
Cyclic imides are inhibitors of tumor necrosis factor .alpha. and can be used to combat cachexia, endotoxic shock, and retrovirus replication. A typical embodiment is 2-(2,6-dioxo-3-piperidinyl)-4-azaisoindoline-1,3-dione.
