Total synthesis of leucinostatin A, a modulator of tumor‐stroma interactions, using asymmetric catalyses, a nitroaldol reaction, thioamide‐aldol reaction, Strecker‐type reaction, and alcoholysis of 3‐methylglutaric anhydride, is described. We demonstrated the applicability of the established catalytic asymmetric processes to the synthesis of molecules with a complex structure. Careful analysis of the
描述了使用不对称催化,硝基羟醛反应,硫代酰胺-羟醛反应,Strecker型反应和3-甲基戊二酸酐的醇解反应来合成肿瘤-基质相互作用的调节剂亮氨酸抑制素A。我们证明了已建立的催化不对称过程对具有复杂结构的分子合成的适用性。仔细分析NMR数据,HPLC图谱和生物学活性后发现,亮氨酸抑素A的正确结构是所报道结构的差向异构体形式。AHMOD残基中的仲醇具有R构型。
