The intriguing structure of 1, a longstanding challenge in natural product synthesis, has been the subject of multiple revisions and has been confirmed through total synthesis. The route commences from a renewable furan starting material and features a number of unusual transformations (rearrangements, bromocyclization, P(V)-based phosphate installation) to arrive at the target in 15 steps. As the route was designed to enable access to both enantiomers, its absolute configuration could be assigned using a bioassay on (+)-1 and (-)-1.

Tagetitoxin的全合成

1 的有趣结构是天然产物合成中长期存在的挑战,已成为多次修订的主题,并已通过全合成得到证实。该路线从可再生呋喃起始材料开始,并具有许多不寻常的转化(重排、溴环化、基于 P(V) 的磷酸盐安装),以通过 15 个步骤到达目标。由于该路线设计为能够获得两种对映异构体,因此可以使用 (+)-1 和 (-)-1 上的生物测定来确定其绝对构型。
