Model amino acidester conjugates bearing heterocycles with a thiocarbonyl group (thiocoumarins and thioquinolones) were prepared by a thionation reaction of the corresponding carbonyl precursors, with the aim of obtaining conjugates with higher photosensitivity at longer wavelengths. Photolysis studies were carried out under irradiation at different wavelengths in a photochemical reactor (250, 300
