A new component for the solid phase peptide synthesis of lipopeptide, 2-[(4R,5R)-5-([(9H-fluoren-9-yl)methoxy]carbonylaminomethyl}-2,2-dimethyl-1,3-dioxolan-4-yl)methoxy]acetic acid (2), was designed and synthesized from (−)-2,3-O-isopropylidene-D-threitol (3) in 4 steps. The key step was the selective alkylation of 3 with benzyl bromoacetate in the presence of Cs2CO3. Vasoactive intestinal peptide (VIP)-lipopeptide (1) incorporating this linker was synthesized by solid phase peptide synthesis.
设计了一种用于固相合成脂肽的新组分 2-[(4R,5R)-5-([(9H-芴-9-基)甲氧基]羰基氨基甲基}-2,2-二甲基-1,3-二氧戊环-4-基)甲氧基]乙酸 (2),并以 (-)-2,3-O-isopropylidene-D-threitol (3),分 4 步设计和合成。关键步骤是在 Cs2CO3 存在下用溴乙酸苄酯对 3 进行选择性烷基化。通过固相肽合成法合成了含有这种连接物的血管活性肠肽(VIP)-脂肽(1)。
