  Palladium(0)-Catalyzed Coupling of Organozinc Iodide Reagents with Bromopyridines:  Synthesis of Selectively Protected Pyridine-Containing Azamacrocycles

  摘要：

  The synthesis of azamacrocycles in which the ring nitrogens are regioselectively functionalized is described. An organozinc palladium(0)-catalyzed coupling with an appropriately functionalized bromopyridine generated a key intermediate, which was transformed in two steps to a desired precursor and subjected to an intramolecular N-alkylation to effect a macrocyclization affording selectively protected azamacrocycles 1-3.
