Oxidation of nitrogen-based methyl heteroaryls with molecular oxygen resulted in the formation of the corresponding benzyl alcohols. While experimentally easy and amenable to large-scale preparations, this approach has limitations with respect to the particular nature of heterocyclic substrates. Using this methodology, the title compound, 2-[N-(tert-butoxycarbonyl)amino]-4-pyridinecarbaldehyde, considered to be a versatile pharmaceutical intermediate, was prepared on a multigram scale.
基于分子氧的含氮甲基杂芳烃氧化反应生成相应的苄醇。尽管这一方法实验上简单且适合大规模制备,但它对于特定的杂环底物有局限性。利用这一方法,我们成功地制备了标题化合物,即2-[N-(叔丁氧羰基)氨基]-4-吡啶甲醛,这是一种被认为用途广泛的药物中间体,其制备规模达到了多克级。
