construction of the (E)- and (Z)-γ-oxo-α,β-alkenoic ester skeletons from readily accessible vinyl propargylic alcohols through modified redox isomerization was uncovered. This approach manifested its high simplicity and efficiency with excellent tolerance of functional substituents, which led to the straightforward structural modifications of various natural products and efficient total syntheses of melodienone
揭示了一种显着的碱基促进方法,用于通过改性氧化还原异构化从易于获得的乙烯基炔丙醇快速构建 ( E )- 和 ( Z )-γ-氧代-α,β-链烯酸酯骨架。该方法具有高度的简单性和高效性,并且对功能取代基具有出色的耐受性,这导致了各种天然产物的直接结构修饰,并在 4 个线性步骤内高效地全合成了 melodienone、hommelodienone、isomelodienone 和 homoisomelodienone。
