Application of SiO 2 nanoparticles as an efficient catalyst to develop syntheses of perimidines and tetraketones

Abstract: In this paper, we explore the catalytic activity of SiO 2 nanoparticles (NPs) as an eco-friendly, efficient and reusable catalyst in the synthesis of 2,3-dihydro-1H-perimidines as well as tetraketones. For tetraketones syntheses, a si

Synthesis, Structure, and Biological Activities of 10-Substituted 3,3,6,6-Tetramethyl-9-Aryl-3,4, 6,7,9,10-hexahydroacridine-1,8(2H,5H)-dione Derivatives

A series of 10-substituted-3,3,6,6-tetramethyl-9-aryl-3,4,6,7,9,10-hexahydroacridine-1,8(2H,5 H)-dione derivatives 2 were synthesized by reaction of compounds 1 with amines. The compounds 1 were effectively prepared by 5,5-dimethylcyclohexane-1,3-dione an

Merging supramolecular catalysis and aminocatalysis: Amino-appended β-cyclodextrins (ACDs) as efficient and recyclable supramolecular catalysts for the synthesis of tetraketones

Well-designed amino-appended β-cyclodextrins (ACDs) with an amino side chain of different lengths at the primary face of β-CD were synthesized and employed in the catalytic synthesis of a series of tetraketones as supramolecular catalysts in water for the first time. Yields of 58-97% were obtained with up to 30 examples of substrate. The catalyst could be recycled easily, while a 92% yield and 84% rate of catalyst recovery could be achieved after 8 cycles of catalyst recycling. Moreover, a catalytic mechanism merging supramolecular catalysis and aminocatalysis could be proposed through detailed 1D and 2D NMR, ESI-MS and Job plot analyses. This protocol retained the promising characteristics of ambient temperature, green medium, simple operation, broad substrate scope, excellent yields, superb catalyst recycling performance and unique catalytic mechanism.
