In the preceding communication we described the synthesis of tetrahydropyridazine-3-carboxylic acids and their incorporation into peptides. We have also prepared the tripeptide 2 which is contained in the antibiotic antrimycin Dv 15. We now report on the preparation of the building blocks 1 and 4 and their coupling with 2 to give the protected antrimycin Dv 14. The deprotection of this heptapeptide constitutes the total synthesis of antrimycin Dv.
在前文中,我们描述了四氢
吡嗪-3-
羧酸的合成及其并入
多肽的过程。我们还制备了三肽2,该三肽包含在抗生素
安曲霉素Dv 15中。现在我们报告了构建单元1和4的制备,以及它们与2的耦合,从而得到保护型的
安曲霉素Dv 14。这个庚肽的去保护步骤构成了
安曲霉素Dv的完全合成。
