The rhodium-catalysed direct ortho-arylation of protected racemic 2-tert-butyl tyrosine has been developed. The subsequent removal of the tert-butyl group yields the 2-arylated tyrosine which can undergo further rhodium-based arylation at the 6-position. In one instance a product formed by further arylation of the diarylated species was isolated.
