  Water-Promoted Synthesis of Enaminones: Mechanism Investigation and Application in Multicomponent Reactions

  摘要：

  Highly stereoselective synthesis of Z-enaminones bearing reactive secondary amino group has been successfully performed in water using tertiary amino group functionalized enaminones under ambient conditions. An interesting promotion effect of water on the reaction via hydrolysis-dehydration condensation has been observed through a designed isotope labeling experiment.

  A one-pot three-component Biginelli-like reaction of enaminones, aldehydes with urea/thiourea in the presence of 2-pyrrolidonium bisulphate as an acidic ionic liquid catalyst for the preparation of 6-unsubstituted dihydropyrimidinones is described. The excellent yield, short reaction time, simple procedure and avoidance of the use of organic solvents are some advantages of this method.
