A one-pot synthesis of urea-substituted diarylethanes and dibenzoxanthenes starting from 1-(2,2dimethoxyethyl)ureas and phenols has been developed. The approach uses readily available reagents and catalysts, requires mild reaction conditions and provides the target compounds in good to high yields.
