Synthesis of a fluorinated analog of 1-aminocyclopropane carboxylic acid
Sloan, Milton J.,Kirk, Kenneth L.
, p. 1677 - 1680 (2007/10/03)
A convenient synthesis of 2-fluoro-1-aminocyclopropane-1-carboxylic acid is described. Cyclopropanation of ethyl 2-(3,4-dimethoxyphenyl)-3-fluoroacrylate followed by Curtius rearrangement, oxidative cleavage of the aromatic ring, and deprotection, produced the α-amino acid.
