Hydroxyphosphoric acids display the unique biological activities, and they have some attractive prospects as clinical drug moleculars. Herein, a new approach for the synthesis of γ-oxo-phosphonates (the precursor of hydroxyphosphoric acid) has been established through the semipinacol rearrangement tactic involved the photo-induced phosphorus radical process. Most important, this transformation is avoid of the external oxidants, and occurs very well under the sunlight irradiation, meanwhile the γ-oxo-phosphonate was easily derivatized to obtain γ-hydroxyphosphoric acid, thus highlights the synthesis value of this method.

Reaction of aryl pyridyl ketones 1 with vinylmagnesium bromide followed by acetylation of the products 2 with acetic anhydride/Et3N and with 4-(dimethylamino)pyridine (DMAP) as a catalyst gave acetates 3 in high yields.Treatment of acetates 3 with dimethylamine in the presence of a palladium catalyst produced a mixture of E and Z isomers of 3-aryl-3-pyridylallylamines 4.
