Trifluoroethanol as a Metal-Free, Homogeneous, and Recyclable Medium for the Efficient One-Pot Synthesis of Dihydropyrimidones
摘要:
Trifluoroethanol is an efficient and recyclable medium in promoting one-pot, three-component condensation reactions of beta-ketoesters, aldehydes, and urea (or thiourea) to afford the corresponding dihydropyrimidones in good yields. This protocol does not require the use of an acid or base catalyst.
The present invention concerns compounds of following general formula (I): (Formula I) and their pharmaceutically acceptable salts, their method of preparation and their uses, notably as anticancer agent.
