A newroute for the synthesis of highly substituted benzenoids has been developed. Key steps include the conversion of unsaturated lactone 7 to carboxy substituted cyclohexenone 8 followed aromatization to give phenol 9. The phenolic functionality provides a handle for further modification to give substituted benzenoids of type 2.

A facile synthesis of substituted diaryliodonium tosylates (toluene-p-sulfonates) was developed, based on the treatment of substituted aryltributylstannanes with Koserâs reagent [hydroxy(tosyloxy)iodobenzene]. In this manner, several new diaryliodonium salts, bearing one or more substituents on one aryl ring, were prepared in useful yields under mild conditions (dichloromethane, room temperature, 2 h).

Copper(I) is rendered catalytically viable in the presence of thiolate by the design of a small molecule chemical analogue of the metallothionein system in which an N-O reactant serves the same conceptual purpose of the S-S reactant of the biological system.
