  Macrocyclization studies and total synthesis of cyclomarin C, an anti-inflammatory marine cyclopeptide

  摘要：

  The studies on macrocyclization at possible sites toward the total synthesis of cyclomarin C are described. The results showed that both Trp and Phe derivatives involved in the target could not be the terminals of the final linear peptide precursors. Additionally, preparation of corresponding dipeptides with an N-methyl amide bond is not favorable in the synthesis of linear precursors. Site d was finally proved a proper site for the cyclopeptide formation, and the corresponding head-to-tail macrocyclization was achieved under mild conditions and gave repeatable and satisfactory yields.

  amino acids, constituents of cyclomarin A, are described. The protected N-methylhydroxyleucine 2 was synthesized using Evans’ asymmetric azide-transfer reaction. The unusual amino acid 3 was prepared via diastereoselective methylation of the l-aspartic acid derived lactone 13. The stereoselective formation of threo-β-methoxyphenylalanine 4 was performed via aldol reaction using Schöllkopf's chiral glycine

  描述了四种非常规氨基酸的立体选择性合成，它们是环marinA的组成部分。使用Evans的不对称叠氮化物转移反应合成了被保护的N-甲基羟基亮氨酸2。通过L-天冬氨酸衍生的内酯13的非对映选择性甲基化制备了不寻常的氨基酸3。使用Schöllkopf's手性甘氨酸烯醇酸酯通过醛醇缩合反应进行苏-β-甲氧基苯基丙氨酸4的立体选择性形成。通过AQN配体促进的Sharpless区域逆向不对称氨基羟基化方案实现了N-反向的戊烯基色氨酸5的合成。
