The straightforward synthesis of trispyrimidonamides as a new class of α-helix mimetics is reported. Because of the versatility of our synthetic protocol, a variety of side chains including aliphatic, basic, aromatic, and heteroaromatic residues were included. A comprehensive conformational analysis revealed that in polar solvents a trimeric compound adopts conformations that can lead to i, i + 4,
据报道,三嘧啶酰胺可作为一类新的α-螺旋模拟物直接合成。由于我们合成方案的多功能性,因此包括脂肪族,碱性,芳族和杂芳族残基在内的各种侧链都包括在内。全面的构象分析表明,在极性溶剂中,三聚体化合物采用的构象会导致i,i + 4,i + 8或i,i + 8侧链取向。这表明,与传统的i,i + 4相比,三嘧啶酰胺类有望成为有希望的α-螺旋模拟物,以靶向分布在更大范围的α-螺旋界面角度范围内的热点。我+ 7例。
