3-Deoxy-d-manno-oct-2-ulosonic acid (Kdo) biosynthetic pathway is a promising target in antibacterial drug discovery. Herein, we report the total synthesis of 6-amino-2,6-dideoxy-α-Kdo in 15 steps from d-mannose as a potential inhibitor of Kdo-processing enzymes. Key steps of the synthetic sequence involve a Horner–Wadsworth–Emmons reaction for the two-carbon chain homologation followed by either a

生物合成途径是在抗菌药物发现有希望的靶点。在此,我们报告了 6-
氨基-2,6-双脱氧-α-Kdo 在 15 个步骤中从d-
甘露糖作为 Kdo 加工酶的潜在
抑制剂的全合成。合成序列的关键步骤包括用于双碳链同源化的 Horner-Wadsworth-Emmons 反应,然后是 6 -exo-trig Pd 催化的还原环化或串联 Staudinger/aza-Wittig 反应,同时伴随 α-亚
氨基酯还原,使类似 Kdo 的六元氮杂环的α-立体选择性形成成为可能。
