Crosslinking amino acids are naturally existing protein crosslinkers. Herein, we described the synthesis of several novel bis-amino acids constituted of serine, alanine, lysine, and tyrosine with click chemistry. The Huisgen 1,3-dipolar cycloadditions between azido- and alkyne-functionalized amino acids can be easily realized in the presence of catalytic amount of CuSO4 and Na ascorbate. In addition
交联氨基酸是天然存在的蛋白质交联剂。在这里,我们用点击化学描述了由丝氨酸,丙氨酸,赖氨酸和酪氨酸组成的几种新型双氨基酸的合成。在催化量的CuSO 4和抗坏血酸钠存在下,叠氮基和炔基官能化氨基酸之间的Huisgen 1,3-偶极环加成反应很容易实现。另外,还使用蒽,荧光素和苯并噻二唑作为荧光团制备了荧光双氨基酸衍生物。用对称的双炔苯并噻二唑,可以合成带有两个不同氨基酸部分的不对称衍生物。
