    used as a catalyst for the synthesis of a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products. It was observed that only 10 mg of the catalyst was enough to catalyze these reactions under mild conditions, and the corresponding products were obtained in high to excellent yields. Moreover, the catalyst could be repeatedly used for at least five times without a noticeable decrease

    A series of pyrimidinone derivatives were efficiently synthesized using PEG-SANM nanocomposite as the solid acid nanocatalyst under mild and solvent-free conditions. The generality of the process was successfully demonstrated by variation of the starting materials. Also, large-scale synthesis of products occurred readily in the presence of this nanocatalyst. This new method eliminated the use of organic

    A regioselective Biginelli-like reaction of alicyclic mono-ketones, aromatic aldehydes, and urea in ionic liquid [BPY]BF4 has been investigated. The process is controlled by the size of alicyclic mono-ketones and the steric hindrance of aromatic aldehydes. The reaction of cyclopentanone with urea and aromatic aldehydes afforded 7-arylidene-3,4,6,7-tetrahydro-4-aryl-1H-cyclopenta[d]pyrimidin-2(5H)-ones
