基于固相载体的假稀释效应, 设计并合成了由赖氨酸为前体结构衍生的氮杂大环化合物8, 9, 10, 12及13. 合成中的关键构件是在固相树脂上肽链的N端键合的二个相邻的赖氨酸残基, 并以溴乙酸为桥连组份, 先后经酰化及亲核取代(SN2)反应完成三氮杂十六元环骨架的构建. 5种粗产物的总收率在68.9%～86.1%之间, 并全部经氨基酸组成分析及ESI-MS分析表征.

Triaza-macrocyclic compounds, based on the pseudo-dilution effect on solid support, were designed and synthesized. The key building blocks for cyclization were two lysine residues and bromoacetic acid as the bridging components via acylation-SN2 reaction in sequence. By present procedure, five target compounds 8, 9, 10, 12 and 13 with trinitrogen atoms in a 16-membered ring were obtained in good overall yields of 68.9%～86.1% and characterized by amino acid analysis and ESI-MS.

Key words: nitrogen containing macro-ring, peptide structure modification, solid-phase synthesis
