Sarain A is a complex macrocyclic marine alkaloid extracted from sponges of the order Haplosclerida. It is likely that this alkaloid shares a common origin with manzamine alkaloids, also extracted from sponges of the same order. In this paper, new concepts concerning this origin are presented and constitute the basis for a synthetic strategy. A preliminary evaluation of this strategy is presented and
Sarain A 是一种复杂的大环海洋生物碱,从 Haplosclerida 目海绵中提取。这种生物碱很可能与同样从海绵中提取的 manzamine 生物碱有共同的来源。在本文中,提出了有关此起源的新概念,并构成了综合策略的基础。提出了对该策略的初步评估,并作为第一个结果,通过五步获得双环中间体 43。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
