数種の生物活性天然物の不斉全合成

抄録

Asymmetric total syntheses of some biologically active natural products are reviewed. The present methods rely on the novel application of the readily available optically active compounds as a chiral synthons that are used as a chiral source in the asymmetric induction and as a carbon framework of the target molecules. Asymmetric syntheses of some Amaryllidaceae alkaloids, maritidine and galanthamine by the use of L-tyrcsine, and the antitumor lignans, steganacin and related lignans by the use of (S)-γ-hydroxymethyl γ-butyrolactone as a chiral synthon are described.
