We report here a novel method for the modular synthesis of highly substituted piperazines and related bis-nitrogen heterocycles via a palladium-catalyzed cyclization reaction. The process couples two of the carbons of a propargyl unit with various diamine components to provide nitrogen heterocycles in generally good to excellent yields and high regio- and stereochemical control.

The synthesis of [ONNO]-type robust Salophan ligands featuring tertiary nitrogen donors is described for the first time. By varying the substitution pattern on the aromatic bridge and on the phenolate rings, four ligands possessing a broad scope of electr
