The synthesis and photochemistry of 3-oxo-3H-benzopyran derivatives linked through ester, anhydride, urethane and carbonate bonds to representative l-amino acids, at the amino and carboxylic acid groups at the main chain or the hydroxyl group at the side chain, were carried out. The stability to photolysis of the resulting conjugates was studied at different wavelengths of irradiation (254, 300 and
3-氧代-3 H-苯并吡喃衍生物的合成和光化学反应,这些酯通过酯,酸酐,氨基甲酸酯和碳酸酯键与代表性的I-氨基酸相连,位于主链的氨基和羧酸基团或侧链的羟基上,进行了。在不同的照射波长(254、300和350 nm)下研究了所得共轭物对光解的稳定性,其中酸酐和酯键在所研究的条件下最敏感。
