We report a catalytic reductive alkylation reaction of primary or secondary amines with carboxylicacids. The two-phase process involves silane mediated direct amidation followed by catalytic reduction.
Catalytic Michael additionreaction represents a fundamental importance in organic synthetic chemistry. Whereas corresponding conversions toward intrinsically low reactive enamide remains an ongoing challenging. We herein report a copper-catalyzed conjugate addition of allenes to β-substituted alkenyl amides, one of the most challenging Michael acceptors. The present method utilizes readily available
