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
光化学键断裂反应可能在化学,生物有机化学和药物化学中有用。我们先前曾报道过在中性pH下水溶液中的8-喹啉基磺酸盐(8-QS)衍生物发生光化学裂解反应,我们建议通过激发三重态进行。在本报告中,我们报告了一些新的可光裂解的8-QS衍生物的合成,其中在7位上引入了卤素原子或硝基,以试图改善光反应性并在其上产生红移。照射波长。溴和碘的引入可能导致光反应加速约1.5倍,这可能是由于重原子效应所致。还发现7-硝基-8-QS在> 360 nm处吸收,因此,
