Various protected β2-amino acids can be prepared by radicaladdition of β-phthalimido-α-xanthyl propionic acid, both as the free acid or as the ethyl ester. Successive radicaladditions provide access to more complex structures. In the case of the free acid, addition to certain heteroaromatics leads directly to β-heteroarylethylamines through spontaneous decarboxylation of the intermediate adduct.
