reaction of simple aromatic acetals and ketals is described. The deprotection is highly efficient under optimized conditions. The aromatic ring confers the photoreactivity to the compounds. The efficiency of the process depends on the structure of the acetal moiety. The common minor side reaction, the photooxidation, becomes the major reaction pathway in the cases of cyclic acetals. The use of photon
描述了一种新型的简单的芳香族缩醛和缩酮的光脱保护反应。在优化条件下,脱保护非常有效。芳环赋予化合物光反应性。该方法的效率取决于缩醛部分的结构。在环缩醛的情况下,常见的次要副反应即光氧化成为主要的反应途径。仅将光子用作试剂使该方法对于缩醛脱保护特别有吸引力。
