The total synthesis of cyanolide A has been achieved in 14 steps from commercially available (S)-2-ethyloxirane, exploiting the palladium-catalyzed intramolecular alkoxycarbonylation as the key step to construct the tetrasubstituted cis-tetrahydropyran ring with high stereoselectivity.
通过14个步骤,利用钯催化的分子内烷氧基羰基化反应作为关键步骤,从市售的(S)-2-乙基环氧乙烷中合成了氰基内酯A,从而构建了具有高立体选择性的四取代顺式四氢吡喃环。
