N-(Coumarin-3-ylcarbonyl)benzotriazole 已与游离氨基酸、N-末端保护的赖氨酸和二肽偶联,以提供荧光氨基酸和二肽(产率 76-89%),并保留原始手性。N α - 和 N e -香豆素标记的赖氨酸通过简单的两步程序获得。N α -Cbz- N e -(Coumarin-3-ylcarbonyl)-L-lysine 被证明是一种光学活性荧光标记,用于在溶液相合成中标记氨基酸。
α-Aminoxy acid conjugates and hybrid α-aminoxy dipeptide conjugates showing blue to green fluorescence (with quantum yields 0.23-0.71) were synthesized (75-92% yield) from N-acylbenzotriazoles. 7-Methoxycoumarin derivatives were obtained (quantum yields φ 0.35-0.71) that could be suitable for peptide assays. The wavelengths of the absorption maxima (λAbs) and the fluorescence emission maxima (λEm)
N-(Coumarin-3-ylcarbonyl)benzotriazole has been coupled with free aminoacids, N-terminal-protected lysines and dipeptides to afford fluorescent aminoacids and dipeptides (76-89% yield) with retention of original chirality. N α - and N e -Coumarin-labeled- lysines are obtained by simple, two-step procedures. N α -Cbz- N e -(Coumarin-3-ylcarbonyl)- L-lysine is demonstrated to be an optically active
