A rapid method is reported for the preparation of biotinylated 4-amino-D-phenylalanine(D-Aph) with Fmoc as the protecting group at the α-amino. Different coupling reagents and conditions were studied to get the biotinylated compound. Coupling reagents like 1-[bis(dimethylamino)methylene]-1H-benzotriazolium 3-oxide hexafluorophos-phate and BOP were found to be very efficient. Biotinylated Boc-L-Aph and biotinylated Fmoc-L-lysine were also successfully prepared by this method.
本研究报道了一种以 Fmoc 为 α-氨基保护基制备生物素化 4-氨基-D-苯丙氨酸(D-Aph)的快速方法。为了得到生物素化的化合物,我们研究了不同的偶联试剂和条件。研究发现,1-[双(二甲基氨基)亚甲基]-1H-苯并三唑鎓 3-氧化物六氟磷酸盐和 BOP 等偶联试剂非常有效。该方法还成功制备了生物素化 Boc-L-Aph 和生物素化 Fmoc-L-赖氨酸。
