β‐ketothioesters from α‐oxo ketene N,S‐acetals has been developed. In this acid‐catalyzed reaction, the amino group, including both alkylamino and arylamino groups, of ketene N,S‐acetals can be easily displaced in the presence of H2O as nucleophile (hydrolysis) instead of the alkylthiol group reported.
已开发出一种有效的策略,用于由α-氧代乙烯酮N,S-乙缩醛酸催化合成β-酮硫酯。在这种酸催化的反应中,乙烯酮N,S-缩醛的氨基(包括烷基氨基和芳基氨基)可以在存在亲核试剂(水解)的H 2 O的情况下轻松取代,而不是所报道的烷基硫醇基团。
