The total synthesis of plakotenin, a cytotoxic marine natural product, using a biomimetic Diels–Alder reaction is described in detail. Two approaches were used, whereby the Diels–Alder reaction occurs at different stages of the synthesis. Homo‐ and nor‐plakotenin, related natural products, were also prepared, as well as iso‐plakotenin, a diastereoisomer of plakotenin. The syntheses prove the relative
详细介绍了使用仿生Diels-Alder反应的细胞毒性海洋天然产物普拉克tenin的全合成。使用了两种方法,Diels-Alder反应发生在合成的不同阶段。智人-和也不-plakotenin,相关的天然产品,也制备,以及ISO -plakotenin,plakotenin的对映异构体。合成证明了后者的相对和绝对立体化学。在选定的化合物上研究了白屈菜素的化学生物学特性。
