The antibiotic agent fumimycin has been synthesized for the first time. This natural product was found to inhibit the bacterial peptide deformylase and may represent a lead structure to a class of novel antibacterials. Our synthetic strategy towards fumimycin involved the following steps: Dakin oxidation of an aldehyde functionality, conversion of an oxime through radical fragmentation to form an
抗生素药物泛霉素首次被合成。发现该天然产物抑制细菌肽去甲酰基酶,并且可能代表一类新型抗菌剂的先导结构。我们对氟米霉素的合成策略涉及以下步骤:醛基官能团的达金氧化,通过自由基裂解将肟转化为N-二苯基磷酰基,通过向酮亚胺上加1,2加成α-三取代胺,进行克莱森重排,然后进行过渡金属催化的烯烃异构化,以安装丙烯基链并进行最终酰胺化。
