Described is a synthesis of (−)-senecionine, the best-known hepatotoxic, 12-membered pyrrolizidine alkaloid of retronecine type. Integerrinecic acid lactone methyl ester was converted into protected senecic acid, which was regioselectively coupled with (+)-retronecine, achieving the first synthesis of (−)-senecionine.
描述了 (-)-senecionine 的合成,这是最著名的具有肝毒性的 12 元吡咯里西啶类型的 retronecine 生物碱。Integerrinecic acid 内酯甲酯被转化为受保护的 senecionic 酸,其与 (+)-retronecine 区域选择性偶联,实现了 (-)-senecionine 的首次合成。
