Total synthesis of prelaureatin, which is an 8-membered cyclic ether isolated from red alga Laurencia nipponica, has been achieved through a process including stereoselective introduction of two allyl groups starting from galactose pentaacetate, cleavage of the hexose ring, and transformation of an acyclic triene into an oxocene by selective ring-closing metathesis.
从红藻 Laurencia nipponica 中分离出的 8 元环醚 prelaureatin 的全合成是通过一个过程实现的,该过程包括从五乙酸半乳糖开始立体选择性地引入两个烯丙基,裂解六糖环,并通过选择性闭环偏析将无环三烯转化为氧代二烯。
