A study of the development of reaction conditions for implementation of an activated Ullmann diaryl ethercondensation reaction that may be conducted without amino acid racemization and that has proven suitable for incorporation of a selectively-protected catechol is described and its application to the synthesis of l,l-isodityrosine (1) is detailed.
