SbCl3 as an Efficient Catalyst for the One-pot Synthesis of Highly Substituted Piperidines
Highly substituted piperidines were synthesized via the condensation of aromatic aldehydes and aromatic amines with β-ketoesters in the presence of antimony(III) chloride at ambient condition. This reaction has any advantages such as easy work-up, clean procedure, and good yields.
متن کاملSulfonated Porous Carbon (SPC): An efficient and recyclable solid acid catalyst for one-pot three-component synthesis of 2,3-dihydroquinazolin-4(1H)-ones under solvent-free conditions
A simple and efficient procedure has been developed for the synthesis of 2,3-dihydroquinazolin-4(1H)-ones derivatives under solvent-free conditions. This method uses the condensation of isatoic anhydride, aldehydes, and amines in the presence of a catalytic amount Sulfonated Porous Carbon (SPC). One of the important advantages of the new method is that the SPC could be recycled and reused.

متن کاملCdS nanoparticles: An efficient, clean and reusable heterogeneous catalyst for one-pot procedure for synthesis of 3,4-Dihydropyrimidin-2(1H)-ones in solvent-free conditions
3,4-Dihydropyrimidinones and their derivatives are synthesized via Biginelli routes involving an aromatic aldehydes, ethylacetoacetates and urea in one-pot procedure by using CdS nanoparticles as efficient heterogeneous catalyst in solvent-free conditions. Compared with classical Biginelli reaction reported in 1893, this new method provides much improved modification in terms of simplicity. The...
