UV photolysis of protected glycines in the presence of di-tert-butyl peroxide, benzophenone and substituted toluenes is shown to lead to selective alkylation at the α-position. Phenylalanines are isolated in yields of generally >50% (based on recovered starting material).

Phenylalanines can be prepared on UV photolysis of protected glycines in the presence of di-tert-butylperoxide, substituted toluenes and the photosensitiser benzophenone. These reactions, which lead to highly selective mono-alkylation at the α-position of glycines, involve coupling of captodative α-glycine radicals with benzyl radicals. This method can be used to selectively alkylate a variety of
