Functionalized enamines, including β-enaminoesters were synthesized using in situ generated HMDS amide bases via the combination of aminosilanes and fluoride salts.
使用在场生成的HMDS酰胺碱通过氨基硅烷和氟化盐的组合合成了包括β-烯胺酯在内的官能化恩酰胺。
Palladium-Catalyzed Oxidative Amination of Activated Olefins with N-Alkyl Anilines for Synthesis of Tertiary (E)-Enamines
An efficientpalladium-catalyzed oxidative amination of olefins with secondary anilines for the synthesis of tertiary (E)-enamines has been developed. Trimethylacetic acid (PivOH) played an important role in the reaction. This protocol tolerates a range of functional groups and is a reliable method for direct synthesis of tertiary (E)-enamines in high yields undermildconditions.
