for the O‐arylation of the sidechain of tyrosine usingtriarylbismuthreagents is reported. The reaction is performed in dichloromethane under oxygen at 50 °C in the presence of pyridine, is promoted by copper diacetate, shows excellent scope and functional group tolerance, and retains the integrity of the chiral center. The reactivity of other amino acids possessing a nucleophilic sidechain under these

A fast, high-yielding synthesis of diaryl ethers with use of mild and metal-free conditions has been developed. The scope includes bulky ortho-substituted diaryl ethers, which are difficult to obtain by metal-catalyzed protocols. Halo-substituents, racemization-prone amino acid derivatives, and heteroaromatics are also tolerated. The methodology is expected to be of high utility in the synthesis of complex molecules and in the pharmaceutical industry.
