The C-1–C-12 segment of the amphidinolides T1–T5 has been synthesised in an efficient manner. The key transformations are highly diastereoselective rearrangement of an oxonium ylide, or metal-bound ylide equivalent, produced by intramolecular reaction of a copper carbenoid with an allylic ether, and macrocyclic fragment coupling by one-pot ring-closing metathesis and hydrogenation.
Amphidinolides T1-T5的C-1–C-12片段已以有效的方式合成。关键的转变是由铜类化合物与烯丙基醚的分子内反应产生的氧鎓叶立德或与金属结合的叶立德等效物的非对映选择性重排,以及通过一锅式闭环易位和氢化作用进行的大环片段偶联。
