Outlined here are studies exploring the scope of the sequential photoelectrocyclization, [1,5]-hydride shift of conjugated bis-aryl cycloalkenone substrates. We have found not only that the cyclization precursors can be synthesized in a modular fashion but also that the cyclization is efficient and amenable to the presence of a range of cycloalkenones and aromatic systems. Among the interesting discoveries
这里概述的研究探索了顺序光电
化学环化的范围,共轭双芳基环烯酮基质的[1,5]-
氢化物转移。我们不仅发现环化前体可以以模块方式合成,而且环化是有效的并且适合于一系列环烯酮和芳族体系的存在。这项工作有趣的发现之一是,电环化中间体可以质子竞争性地捕获,并且激发态(单峰与三重态)的性质取决于芳族取代。
