A concise total synthesis of (-)-4-desacetoxy-1-oxovindoline is disclosed, bearing a single heteroatom exchange in the core structure of the natural product 4-desacetoxyvindoline. Central to the synthesis is powerful oxadiazole intramolecular [4+2]/[3+2] cycloaddition cascade that formed four C-C bonds, created three new rings, and established five contiguous stereocenters about the new formed central 6-membered ring.
本文公开了(-)-4-去乙酰氧基-1-氧代长春多灵的简洁全合成方法,该方法在天然产物4-去乙酰氧基长春多灵的核心结构中进行了单一杂原子交换。该合成的关键是强大的恶二唑分子内[4+2]/[3+2]环加成串联反应,该反应形成了四个C-C键,生成了三个新环,并在新形成的中心六元环周围建立了五个连续的立体中心。
