N(alpha)-Fmoc-N(epsilon)-[(7-methoxycoumarin-4-yl)acetyl]-L-lysine (N(alpha)-Fmoc-L-Lys(Mca)-OH) 3 is conveniently prepared by benzotriazole methodology (52% over two steps). N-Acylbenzotriazoles Mca-Bt 2, N(alpha)-Fmoc-L-Lys(Mca)-Bt 4, coumarin-3-ylcarbonyl (Cc)-Bt 5, N(alpha)-Fmoc-L-Lys(Cc)-Bt 7 and N(alpha)-(Cc)-L-Lys(Fmoc)-Bt 9 enable the efficient microwave enhanced solid-phase fluorescent labeling of peptides.
N(α)-芴甲氧羰基-N(ε)-[(7-甲氧基香豆素-4-基)乙酰基]-L-赖氨酸（N(α)-芴甲氧羰基-L-赖氨酸(Mca)-OH）3可通过苯并三唑方法方便地制备（两步产率为52%）。N-酰基苯并三唑Mca-Bt 2、N(α)-芴甲氧羰基-L-赖氨酸(Mca)-Bt 4、香豆素-3-羰基（Cc）-Bt 5、N(α)-芴甲氧羰基-L-赖氨酸(Cc)-Bt 7和N(α)-(Cc)-L-赖氨酸(Fmoc)-Bt 9能够实现肽的高效微波增强固相荧光标记。
