Ultrasound-Promoted Synthesis of beta-amino Carbonyl Compounds via a Mannich Reaction Catalyzed by Ionic Liquids

摘要

Background: Mannich reaction is one of the most important carbon-carbon bond formation reactions in organic synthesis. Traditional methods require a large amount of ungreen catalysts or much longer reaction time, which limits the scope of their application. So, a recyclable catalyst with high activity and selectivity is highly appreciated, and the highly shortened reaction time is also very appealing.
