A concise formal synthesis of (+)-neopeltolide (1) has been accomplished. The synthesis demonstrated high atom efficiency employing only one step of functional group protection. Key steps involved iridium-catalyzed double asymmetric carbonyl allylation, palladium-catalyzed intramolecular alkoxycarbonylation, ruthenium-catalyzed olefin isomerization, and ring-closing metathesis.
(+)-neopeltolide(1)的简明形式合成已经完成。合成证明仅使用一个官能团保护步骤即可实现高原子效率。关键步骤包括铱催化的双不对称羰基烯丙基化,钯催化的分子内烷氧基羰基化,钌催化的烯烃异构化和闭环复分解。
