Notoamide S has been suggested to be the final common precursor between two different Aspergillus sp. fungal strains before diverging to form enantiomerically opposite natural products (+)- and (-)-stephacidin A and (+)- and (-)-notoamide B. The synthesis of notoamide S comes from the coupling of N-Fmoc proline with a 6-hydroxy-7-prenyl-2-reverse prenyl tryptophan derivative that was synthesized via
Notoamide S 被认为是两种不同曲霉属之间的最终共同前体。在发散形成对映体相反的天然产物 (+)- 和 (-)-stephacidin A 和 (+)- 和 (-)-notoamide B 之前的真菌菌株。 notoamide S 的合成来自 N-Fmoc 脯氨酸与6-羟基-7-异戊二烯基-2-反向异戊二烯基色氨酸衍生物,通过后期克莱森重排从 6-炔丙基-2-反向异戊二烯化吲哚合成。
