15-oxo-Lipoxin A (15-oxo- LXA) has been identified as a natural metabolite of the fatty acid signaling mediator Lipoxin A. Herein, we report a total synthesis of the methyl ester of 15-oxo-LXA to be used in investigations of potential electrophilic bioactivity of this metabolite. The methyl ester of 15-oxo-LXA was synthesized in a convergent 15 step (9 steps longest linear) sequence starting from 1-octyn-3-ol and 2-deoxy-D-ribose with Sonogashira and Suzuki cross-couplings of a MIDA boronate as key steps.
15-氧代脂氧素A(15-oxo-LXA)已被鉴定为脂肪酸信号介质脂氧素A的天然代谢产物。在此,我们报道了15-氧代-LXA甲酯的全合成,用于研究该代谢产物潜在的亲电生物活性。15-氧代-LXA甲酯是通过一个汇聚式的15步(最长线性9步)序列合成的,从1-辛炔-3-醇和2-脱氧-D-核糖开始,以MIDA硼酸酯的Sonogashira和Suzuki交叉偶联为关键步骤。
