Photochemical bond-cleavage reactions are potentially useful in chemistry, bioorganic chemistry and medicinal chemistry. We previously reported on a photochemical cleavage reaction of 8-quinolinyl sulfonate (8-QS) derivatives in aqueous solution at neutral pH, which we proposed to proceed via an excited triplet state. In this report, we report on the synthesis of some new photocleavable 8-QS derivatives

Tetrazine-Norbornene ligation through inverse electron-demand Diels-Alderreaction has been employed as a novel strategy to immobilize a peptide-based catalyst onto different mesoporoussilica supports. Functionalized silicamonoliths as well as silica particles in packed bed reactors have been applied in the enantioselective flow catalysis of the addition reaction between ß-nitrostyrene and n-butanal.
