The kalimantacins make up a family of hybrid polyketide-nonribosomal peptide-derived natural products that display potent and selective antibiotic activity against multidrug resistant strains of Staphylococcus aureus. Herein, we report the first total synthesis of kalimantacin A, in which three fragments are prepared and then united via Sonogashira and amide couplings. The enantioselective synthetic
Kalimantacins 组成了一个混合聚酮化合物-非核糖体肽衍生的天然产物家族,这些产物对金黄色葡萄球菌的多重耐药菌株显示出有效和选择性的抗生素活性。在此,我们报告了卡里曼泰星 A 的首次全合成,其中制备了三个片段,然后通过 Sonogashira 和酰胺偶联进行了结合。对映选择性合成方法是收敛的,为结构-活性关系研究和临床评估开辟了进一步的卡里曼泰星和类似物的路线。
