摘要
报道了一种可见光促进4-哌啶酮及2,3-二氢-4-喹诺酮的有氧脱氢化方法.研究中通过使用一种二腈基哌嗪化合物(dicyanopyrazine-derived chromophore,DPZ)为光催化剂,能够以令人满意的分离产率(最高75%)分别合成出2,3-二氢-4-吡啶酮与4-喹诺酮.本反应为这两类重要含氮杂环化合物提供了一种直接的、可持续的以及高原子经济性的合成途径.
A visible-light-induced photocatalytic aerobic dehydrogenation of 4-piperidones and 2,3-dihydro-4-quinolones has been developed. By utilizing dicyanopyrazine-derived chromophore（DPZ） as the photocatalyst, the dehydrogenation could provide 2,3-dihydro-4-pyridones and 4-quinolones with satisfactory results（up to 75% yield）. The current methodology presents a direct, sustainable and highly atom-economic approach to access these valuable N-containing heterocycles.
