Hydrogenation of linear ω-azido-pentafluorophenyl esters from mixed oligomers of 6-amino-6-deoxy-d-galactonic acid (or 6-amino-6-deoxy-d-mannonic acid) and 6-aminohexanoic acid gives cyclic peptides containing 14-, 28- and 42-membered ring lactams. Hydrogenation of a tetrameric peptide derived from ε-amino acids gave a 28-membered ring lactam in 79% yield.
从6-氨基-6-脱氧-d-半乳糖酸(或6-氨基-6-脱氧-d-甘露酸)和6-氨基己酸的混合低聚物中氢化线性ω-叠氮基-五氟苯基酯,得到的环肽为14 -,28-和42-元环内酰胺。衍生自ε-氨基酸的四聚体肽的氢化反应产生28元环内酰胺,产率为79%。
