Treat me gently: For a selective synthesis of the unusually sensitive cyclophanic α‐pyrone neurymenolide A, the chosen catalysts must be able to distinguish between six different sites of unsaturation, without scrambling any of the skipped π systems. This challenge was met with a new gold‐catalyzed pyrone synthesis in combination with a molybdenum‐catalyzed ring‐closing alkyne metathesis.
温和地对待我:为选择性合成异常灵敏的α-吡喃酮神经节烯内酯A,所选的催化剂必须能够区分六个不同的不饱和位点,而不会扰乱任何跳过的π系统。新的金催化的吡喃酮合成与钼催化的闭环炔烃复分解反应解决了这一难题。
