S-acetals in water for the switchable synthesis of β-keto thioesters and β-keto amides is reported. In refluxing water, the hydrolysis reactions of α-oxo ketene N,S-acetals in the presence of 1.0 equiv of dodecylbenzenesulfonic acid effectively afforded β-keto thioesters in excellent yield, while β-keto amides were successfully obtained in excellent yield when the hydrolysis reactions were carried
抽象的 据报道,链α-氧代烯酮N , S-缩醛在水中进行环保选择性水解,用于可切换合成β-酮硫酯和β-酮酰胺。在回流水中,α-氧代乙烯酮N , S-缩醛在1.0当量的十二烷基苯磺酸存在下进行水解反应,有效地以优异的产率得到β-酮基硫酯,而当水解时,以优异的产率成功地获得了β-酮基酰胺。反应在3.0当量NaOH存在下进行。 β-酮硫酯和β-酮酰胺的绿色方法避免了使用有害的有机溶剂、硫醇和硫乙酸酯以及胺,这些可能导致严重的环境和安全问题。 Beilstein J. Org. Chem. 2024, 20, 2225–2233. doi:10.3762/bjoc.20.190
