Novel terpene alcohols, oxocrinol (1a), caulerpol (3a), and crinitol (2a), isolated from marine algae, were synthesized by the alkylation of lithium salt of benzenesulfonyl derivatives, 5, 6, and 11 (R = THP; X = SO2Ph) followed by reductive cleavage of SO2Ph and the protecting groups. The present study confirms unequivocally the proposed structures of oxocrinol, caulerpol, and crinitol, respectively.
通过苯磺酰基衍
生物 5、6 和 11(R = THP;X = SO2Ph)的
锂盐烷基化,然后还原裂解 SO2Ph 和保护基,合成了从海洋藻类中分离出来的新型
萜烯醇 oxocrinol (1a)、caulerpol (3a) 和 crinitol (2a)。本研究明确证实了所提出的oxocrinol、caulerpol 和 crinitol 的结构。
