specificity of the noticeable observation on the ICT excited energy state character, which was found in the study of peridinin, we achieved the straightforward synthesis of a series of fucoxanthin short-chain derivatives via the modified-Julia olefination with the aldehyde half segment possessing a β,γ-epoxyketone function. The established method was successfully applied to the synthesis of the epoxy olefin
岩藻黄质是光捕获藻类必需的色素。它表现出高的能量转移效率,以叶绿素一个(> 80%)以及多甲藻素(> 95%)。为了验证在Peridinin研究中发现的有关ICT激发能态特征的显着观察的一般性和特异性,我们通过修饰的Julia烯化反应,实现了一系列岩藻黄质短链衍生物的直接合成。醛半链段具有β,γ-环氧酮功能。所建立的方法已成功地应用于环氧乙烷衍生物的合成,这是一种烯丙基修饰的岩藻黄质类似物。
