preparation of Tröger's base derivatives of natural antibiotics via an amide protocol. The novel heterocyclic Tröger's bases were characterized by a variety of spectroscopic techniques and compound 2b by X-ray crystallography. Incorporation of guanidine as the terminal group in the N-methylpyrrole Tröger's base skeleton opens the possibility for preparation of water soluble derivatives.
从4-氨基-N-甲基吡咯羧酸盐区域选择性地制备Tröger碱的新型类似物,收率很高。二苄基-4,9-甲醇-1,6-二甲基-4,5,9,10-四氢-1 H,6 H-二吡咯并-[3,2- b:3',2'- f ]的催化加氢[1,5]二唑-2,7-二羧酸盐2b导致4,9-甲醇-1,6-二甲基-4,5,9,10-四氢-1 H,6 H-二吡咯并-[3,2- b:3',2'- f ] [1,5]二唑-2,7-二羧酸3它通过酰胺方案用于制备Tröger天然抗生素的基础衍生物。通过多种光谱技术和化合物2b通过X射线晶体学表征了新型的Tröger杂环碱基。在N-甲基吡咯Tröger的基本骨架中引入胍作为末端基团,为制备水溶性衍生物提供了可能。
