N-difluoromethylthiophthalimide reagents that can be easily prepared with commercially available and economical chemicals. These reagents could smoothly react with various nucleophiles, such as Grignard reagents, boronic acids, β-keto esters, and anilines, which affords structurally diverse α-difluoromethylthiolated ketones in good to excellent yields. The formal synthesis of active antifungal compounds positively
以α-二氟硫代甲基化酮骨架衍生物为特征的化合物在药物和农用化学品中特别受关注。在此,我们设计了新型亲电子N-二氟甲基硫代邻苯二甲酰亚胺试剂,可以使用市售且经济的化学品轻松制备。这些试剂可以与各种亲核试剂顺利反应,例如格氏试剂、硼酸、β-酮酯和苯胺,从而以良好至优异的收率提供结构多样的α-二氟甲硫基化酮。活性抗真菌化合物的正式合成肯定了这些试剂的实用性。
