The biologically active guaianolides, zaluzanin C and zaluzanin D, and the stereoisomeric guaianolide, 3-epizaluzanin C, have been synthesized by two different procedures. The stereochemistry at C3 of zaluzanin C has been established to be S configuration by this synthesis.
通过两种不同的程序合成了具有生物活性的愈创木酚内酯--扎鲁扎宁 C 和扎鲁扎宁 D,以及立体异构愈创木酚内酯--3-表扎鲁扎宁 C。通过这种合成方法,确定了扎鲁扎宁 C C3 的立体化学结构为 S 构型。
