Sugar Amino Acids (SAAs) are sugar moieties containing at least one amino and one carboxyl group. The straightforward synthesis of two furanoid SAAs, 3-amino-3-deoxy-1,2-isopropylidene-alpha-D-ribofuranoic acid (f-SAA1) and 3-amino-3-deoxy-1,2-isopropylidene-alpha-D-allofuranoic acid (f-SAA2) starting from diacetone glucose, is described. These SAAs were used as structural templates aiming at new structures
糖氨基酸(SAA)是含有至少一个氨基和一个羧基的糖部分。两种呋喃类SAA的简单合成方法,即3-氨基-3-脱氧-1,2-异亚丙基-α-D-呋喃呋喃甲酸(f-SAA1)和3-氨基-3-脱氧-1,2-异亚丙基-α-描述了从双丙酮葡萄糖开始的D-铝呋喃甲酸(f-SAA2)。这些SAA用作结构模板,旨在用于拟肽药物设计的新结构。f-SAA1与β-氨基酸类似,而f-SAA2与g-氨基酸类似。因此,为了合成f-SAA1的混合,线性和环状低聚物,选择β-高-甘氨酸(β-hGly,也称为β-丙氨酸)作为氨基酸对应物,而选择f-SAA2的低聚物选择了γ-氨基丁酸(GABA)。Fmoc- [f-SAA1-β-hGly](3)-OH(3)和环[f-SAA1-β-hGly](3)(5)类似于线性和环状β肽,具有非常不同的取代方式,与迄今文献中已知的β肽相比,Fmoc- [f-SAA2-GABA](3)-OH(4)与
