the present study, we successfully developed an efficient thiocyanation of carbonyl compounds by using low-toxicity and inexpensive ammonium thiocyanate as the thiocyanate source under visible light in air (O2) at room temperature. This unified strategy is very facile for thiocyanation of various carbonyl compound derivatives (β-keto esters, β-keto amides, pyrazo-5-ones, isoxazol-5-ones, etc.). More
在本研究中,我们利用低毒且廉价的硫氰酸铵作为硫氰酸盐源,在室温下、空气(O 2 )中可见光下成功开发了羰基化合物的高效硫氰化反应。这种统一的策略非常适合各种羰基化合物衍生物(β-酮酯、β-酮酰胺、吡唑-5-酮、异恶唑-5-酮等)的硫氰化。更重要的是,反应顺利进行,无需添加光催化剂和强氧化剂,最终最大限度地减少了化学废物的产生。此外,这种绿色和可持续的合成化学可用于生物相关化合物的后期功能化(LSF),这为在温和的反应条件下实现药物的顺利和清洁的硫氰化提供了独特的机会。
