4-Sulfobenzoic Acid as an Efficient Catalyst for the Preparation of 3,4-dihydropyrimidin-2-(1H)-ones Under Solvent-free Conditions
In this research, one-pot three-component synthesis of 3,4-dihydropyrimidin-2-(1H)-ones havebeen developed using Biginelli reaction from the interaction between ethyl/methyl acetoacetate,aromatic aldehydes, and urea/thiourea in the presence of 4-sulfobenzoic acid as a new, effective,inexpensive, and available bronsted acid. Avoidance of toxic and dangerous solvents, easy isola...
