Cu(ClO4)2.6H2O as an efficient catalyst for the synthesis of 3,4-dihydropyrimidin-2(1H)-ones under solvent-free conditions
Lei, Min,Ma, Lei,Hu, Lihong
, p. 3071 - 3077 (2011)
Cu(ClO4)6H2O efficiently catalyzes the three-component Biginelli reaction of aldehyde,-dicarbonyl compounds, and urea or thiourea under solvent-free conditions to afford the corresponding 3,4-dihydropyrimidin-2(1H)-ones in excellent
Ionic liquids catalyzed Biginelli reaction under solvent-free conditions
Peng, Jiajian,Deng, Youquan
, p. 5917 - 5919 (2001)
3,4-Dihydropyrimidin-2(1H)-ones were synthesised in high yields by one-pot three-component Biginelli condensation in the presence of room temperature ionic liquids such as 1-n-butyl-3-methylimidazolium tetrafluoroborate (BMImBF4) or hexafluorop
Composite of cross-linked chitosan beads and a cyclodextrin nanosponge: A metal-free catalyst for promoting ultrasonic-assisted chemical transformations in aqueous media
Sadjadi, Samahe,Koohestani, Fatemeh
, (2021/05/17)
A novel carbohydrate-based catalytic composite was prepared through covalent decoration of cross-linked chitosan beads with a cyclodextrin nanosponge. In this regard, chitosan beads were fabricated and cross-linked with glutaraldehyde. Subsequently, they
Sulfonic Acid and Ionic Liquid Functionalized Covalent Organic Framework for Efficient Catalysis of the Biginelli Reaction
Yao, Bing-Jian,Wu, Wen-Xiu,Ding, Luo-Gang,Dong, Yu-Bin
, p. 3024 - 3032 (2021/02/05)
A quinoline-linked and ionic liquid-decorated covalent organic framework was prepared by incorporation of a multicomponent Povarov reaction and postsynthetic modification. The imidazolium and sulfonic acid-decorated COF-IM-SO3H can be a highly efficient B
