First synthesis of (+)-α-polypodatetraene (1) and (+)-γ-polypodatetraene (2) was achieved from (+)-albicanol (6) and (−)-drimenol (8), respectively. The absolute structure of natural (+)-2 was established to be (5S,9S,10S)-polypoda-7,13(E),17(E),21-tetraene.
分别从(+)-albicanol (6)和(-)-drimenol (8)首次合成了(+)-α-聚十二碳四烯(1)和(+)-γ-聚十二碳四烯(2)。天然(+)-2的绝对结构被确定为(5S,9S,10S)-聚-7,13(E),17(E),21-四烯。
