Li(OHCH2CH2NH2)(CF3OAC): A novel and homogeneous acidic ionic liquid catalyst for efficient synthesis of 2-amino-4H-chromene derivatives
The ionic liquid Li(OHCH2CH2NH2)(CF3OAC) was found to efficiently catalyze the three-component reaction between different enols, aldehydes, and malononitrile , leading to rapid synthesis of 2-amino-4H-chromene derivatives in fairly high yields. The catalyst is easily prepared, highly stable, simple to handle and recycled for several times without significant loss of activity. The method is simp...
