  Synthesis and Metalation of a Chiral, Pyridine-Strapped, Cyclic Bis(benzimidazole) Ligand

  摘要：

  [GRAPHICS]Synthesis of a chiral, strapped, cyclic bis(benzimidazole) ligand is reported. This compound forms a stable, Jahn-Teller-distorted, octahedral Cu(II) complex in which the elongated axis is positioned within the main macrocycle. The C-2-symmetric bis(benzimidazole) core adopts a highly ruffled conformation with the ortho-substituted benzene rings located anti relative to the pyridine-bearing strap.

  New compounds that are similar in function to tetrapyrrole ligands are provided. The basic framework consists of three classes of homochiral cyclic bis(benzimidazole) ligands: (1) bis(benzamidazoles) having Schiff base linkages; (2) bis(benzimidazoles) with diamime linkages; and (3) bis(benzimidazoles) with diamide linkages. Complexes of these ligands are also provided. The bis(benzimidazole) ligands further comprise a strap that lessens or precludes racemization of ligands or their complexes. These homochiral ligands are useful as catalysts for many types of reactions, including asymmetric epoxidation, epoxide ring opening. Diels-Alder, hereto Diels-Alder, asymmetric oxidation of benzylic hydrocarbons, oxidation of sulfides, hydroxylation, aziridination, cyclopropanation, kinetic resolution of allenes and other cumulenes, and the addition of HCN to imines. Also provided are polymer supports comprising the homochiral bis(benzimidazole) ligands and complexes.
