A new palladium-catalyzed synthesis of 3-amido-substituted β-lactams is reported. This process involves the one-pot coupling of four components, imines, carbon monoxide, and acid chloride, providing a flexible route to construct this class of heterocycle. The generation of β-lactams with two different imines can also be accomplished, providing a method to assemble these products with independent control over five separate substituents.
