dihydroxylated PUFA metabolites derived from docosahexaenoic and arachidonic acids comes from the introduction of the polar head chain at the very end of the synthesis from an advanced, pivotal aldehyde. In terms of divergency this enables late-stage modification of the head group.
采用灵活的策略已成功实现了三个ω-6二羟基化(E,E,Z)-二十二碳三烯的首次全合成。关键特性包括Boland半还原,通过(E,E)-乙二烯生成(E,E,Z)-三烯,以及对tris(tert)的选择性脱保护。-丁基二甲基甲硅烷基)醚。本策略相对于先前合成的源自二十二碳六烯酸和花生四烯酸的非环状二羟基化PUFA代谢物的主要优势在于,在合成的最后阶段,由高级枢轴醛引入了极性头链。在分歧方面,这使得可以对头组进行后期修改。
