An easy and convenient synthetic route to (S)-2-hydroxy-2'-(3-phenyluryl-benzyl)-1,1'-binaphthyl-3-carboxaldehyde (1), capable of recognizing tryptophan by fluorescence has been developed. The binol carboxaldehyde 1 exhibited a high selectivity to L-tryptophan over other examined L--amino acids such as alanine, phenylalanine, glutamine, arginine, lysine, serine, threonine, aspartat, valine, histidine
已开发出一种简单方便的合成路线 (S)-2-hydroxy-2'-(3-phenyluryl-benzyl)-1,1'-binaphthyl-3-carboxaldehyde (1),能够通过荧光识别色氨酸。Binol carboxaldehyde 1 对 L-色氨酸的选择性高于其他已检测的 L-氨基酸,如丙氨酸、苯丙氨酸、谷氨酰胺、精氨酸、赖氨酸、丝氨酸、苏氨酸、天冬氨酸、缬氨酸、组氨酸和半胱氨酸,具有荧光“转-开”信号。此外,1通过不同的荧光增强因子对L-色氨酸比对D-色氨酸表现出更好的对映选择性。
