(Z)-β-Fluoromethylene-m-tyrosine (2) has been prepared by acid hydrolysis of ethyl 2-trifluoroacetylamino-3-(3-methoxyphenyl)-4-fluoro-3-butenoate (1) and its structure established by single crystal X-ray diffraction analysis. Fluorination of the amino acid 2 with acetyl hypofluorite yielded a mixture of products containing fluorine substituted on the ring (3a-c) as well as added across the vinylic
