The invention relates to a method for preparing F-Dopa and
18
F-Dopa and intermediates that are useful in the method. The invention is a method that synthesizes F-Dopa and
18
F-Dopa in good yield with high enantiopurity without the need for further transformations. The method includes the step of reacting a benzaldehyde derivative with a phosphonic acid derivative to produces an olefin intermediate that can be asymmetrically hydrogenated to produce the desired enantiomer.

describe the realization of these requirements with the production of 18F arenes from pinacol‐derived aryl boronic esters (arylBPin) upon treatment with [18F]KF/K222 and [Cu(OTf)2(py)4] (OTf=trifluoromethanesulfonate, py=pyridine). This method tolerates electron‐poor and electron‐rich arenes and various functional groups, and allows access to 6‐[18F]fluoro‐L‐DOPA, 6‐[18F]fluoro‐m‐tyrosine, and the translocator
