The asymmetric synthesis of the unlabeled and [D8]-labeled terminal precursors, 4 ((−)-(S)-dihydroxyverbacine) and 19, respectively, in the biogenesis of the spermine alkaloids aphelandrine (5) and orantine (6), respectively, is described. A partial synthesis of the alkaloid (−)-(S)-[(E)-4-methoxycinnamoyl]buchnerine (10) is also presented.
未标记和 [D8] 标记的末端前体 4 ((-)-(S)-dihydroxyverbacine) 和 19 分别在精胺生物碱 aphelandrine (5) 和 orantine (6) 的生物发生中的不对称合成,分别, 被描述。还介绍了生物碱 (-)-(S)-[(E)-4-methoxycinnamoyl]buchnerine (10) 的部分合成。
