The marine natural product flustramine C from the bryozoan Flustra foliacea was synthesized in five steps and 38% yield starting from Nb-methyltryptamine. The key step is the biomimetic oxidation of the natural product deformylflustrabromine causing selective 1,2-rearrangement of the inverse prenyl group. By 1H,15N HMBC experiments, it is unambiguously shown that the reaction with t-BuOCl commences
以五个步骤合成了来自苔藓苔藓菌的海洋天然产物氟他胺C,从Nb-甲基色胺开始,收率为38%。关键步骤是天然产物去甲酰基氟乙溴的仿生氧化,导致反异戊烯基的选择性1,2-重排。通过1H,15N HMBC实验,明确表明与t-BuOCl的反应始于侧链氮的氯化反应。脱甲酰基氟溴溴本身是通过Danishefsky反相烯丙基化合成的。[反应:请参见文字]。
