A GPI-anchored dipeptide of sperm CD52 antigen was prepared through a convergent synthesis. First, the dipeptide with its C-terminus free and the GPI with its nonreducing end phosphoethanolamine bearing a free amino group were synthesized separately. Then, the two building blocks were coupled with use of EDC/HOBt as the condensation reagent. Finally, the GPI-anchored peptide was deprotected to give the target molecule 1.
通过汇聚合成法制备了精子CD52抗原的糖基磷脂酰肌醇（GPI）锚定二肽。首先，分别合成了C端游离的二肽和非还原端磷酸乙醇胺带有游离氨基的GPI。然后，使用1-乙基-3-(3-二甲基氨基丙基)碳二亚胺盐酸盐（EDC）/1-羟基苯并三唑（HOBt）作为缩合试剂将这两个结构单元偶联。最后，对GPI锚定肽进行脱保护以得到目标分子1。
