The first total syntheses of JBIR-06 and two analogous depsipeptides, 12-membered antimycin-class antibiotics, have been accomplished via Shiina macrolactonization. Comparison of the spectroscopic data of the synthesized compounds with those reported for natural products verified that the absolute configutation of the natural products was (2S,4S,6S,7R,14S).
JBIR-06和两种类似的二肽,十二元抗霉素类抗生素的第一批总合成已通过椎名大内酯化法完成。将合成化合物的光谱数据与天然产物报道的光谱数据进行比较,证实了天然产物的绝对构型为(2 S,4 S,6 S,7 R,14 S)。
