Abstract

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 φ0.35-0.71) that could be suitable for peptide assays. The wavelengths of the absorption maxima (λAbs) and the fluorescence emission maxima (λEm) and the quantum yields (φ) of some coumarin-3-ylcarbonyl aminoxy acid conjugates were comparable to those of the analogous amino acid derivatives.
