Phenolic and non-phenolic oxidative aryl coupling reactions were successful
ly used in the efficient synthesis of diverse natural products and related
compounds in the fields of biphenyls, biscarbazoles and bisnaphthylisoquino
lines. For sterically more hindered biaryls, which consequently show the ph
enomenon of axial chirality, the products were prepared in an atropisomeric
ally pure form. Their absolute axial configurations were assigned mainly by
experimental and computational CD investigations. (C) 2000 Elsevier Scienc
