Thieme Chemistry Journal awardees - Where are they now? Scope of tyrosine O-arylations with boronic acids: Optimized synthesis of an orthogonally protected isodityrosine

The Evans-Chan-Lam variant of the Ullman condensation has been explored to deliver O-arylated tyrosines and tyrosinyl peptides. Key modifications for success were the slow addition of boronic acids to the phenol-catalyst mixture. Selectivity and scope are investigated. Georg Thieme Verlag Stuttgart.
