We report a short and convenient synthesis of two configurationally locked retinals that are important for applications in the context of optogenetics. The C11–C15 cyclopentyl fragments of both retinals were obtained by palladium-catalysed alkoxycarbonylation and merged with the rest of the carbon skeleton through Wittig olefination. The preparation of the required and known ylide precursor was revisited
我们报告了两个构型锁定的视网膜的简短而方便的合成,这对于光遗传学的应用很重要。两种视黄醛的 C11-C15 环戊基片段均通过钯催化的烷氧基羰基化获得,并通过 Wittig 烯化与其余碳骨架合并。重新审视并优化了所需且已知的叶立德前体的制备。这种合成路线能够实现两种视黄醛衍生物的克级制备。
