摘要：

An eco-friendly selective hydrolysis of chain a-oxo ketene N,S-acetals in water for the switchable synthesis of (3-keto thioesters and (3-keto amides is reported. In refluxing water, the hydrolysis reactions of a-oxo ketene N,S-acetals in the presence of 1.0 equiv of dodecylbenzenesulfonic acid effectively afforded (3-keto thioesters in excellent yield, while (3-keto amides were successfully obtained in excellent yield when the hydrolysis reactions were carried out in the presence of 3.0 equiv of NaOH. The green approach to (3-keto thioesters and (3-keto amides avoids the use of harmful organic solvents, thiols and thiolacetates as well as amines, which could result in serious environmental and safety issues.
