phenylalanine as model bifunctional molecules were synthesised to assess its applicability as a photocleavable protecting group for solution phase organic synthesis and in caging applications at longer wavelengths. The behaviour of the corresponding derivatives towards photolysis was evaluated by irradiation at 350 and 419 nm in a mixture of HEPES buffer and acetonitrile or methanol in a photochemical reactor
合成了缬氨酸或苯丙氨酸的 (6-Methoxy-2-oxo-2H-naphtho[1,2-b]pyran-4-yl) 甲酯作为模型双功能分子,以评估其作为溶液相有机物的光裂解保护基团的适用性合成和在更长波长的笼形应用中。相应衍生物对光解的行为通过在光化学反应器中的 HEPES 缓冲液和乙腈或甲醇的混合物中以 350 和 419 nm 的辐射进行评估,然后进行 HPLC/UV 监测。时间分辨荧光测量用于阐明动力学。
