are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an SN2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C
有机化学的基本和高度有价值的转化之一是醇的亲核取代。传统上,这些反应需要采用化学计量危险试剂的策略,并且难以纯化副产物。为了克服这些挑战,在这里,我们报告了一种通过SN2途径实现多元醇转化的简单途径,其中使用蓝光促进的碘化作用由简单的未反应的醇形成烷基碘化物中间体。该方法的范围容许构建CN,CO,CS和CC键的亲核试剂的范围。此外,我们还证明了该方法可用于药物的制备和后期功能化,如巯基内酯,丁氧卡因和普拉莫星的合成所突出。
