A Pd-catalyzed α,β-desaturation of N-protected lactams occurs under mild acidic conditions at room temperature, yielding their conjugated unsaturated derivatives. This reaction demonstrates broad functional group tolerance and offers reactivity distinct from previous desaturation techniques. Lactams featuring diverse ring sizes and substituents positioned at various points undergo smooth transformation.
