The Ambient Temperature Ullmann Reaction and Its Application to the Total Synthesis of (+/-)-Steganacin

The details of a new method for preparing unsymmetrical biphenyls at room temperature by a modification of the classical Ullmann reaction are discussed.An intramolecularly coordinated organocopper reagent is treated with an aryl iodide bearing a potential coordinating ligand to form the biphenyl.Nitrogen and sulfur have been utilized as ligands and as protecting groups for carbonyls.The application of this methodology to the synthesis of the antileukemic steganacin is detailed.
