[source] An efficient one-pot synthesis of 6-aryl-5-cyano-2-thiopyrimidinone derivatives and their piperidinium ionic forms, x-ray crystal structuresJOURNAL OF HETEROCYCLIC CHEMISTRY, Issue 4 2006Saeed Balalaie Three-component condensation of benzaldehyde derivatives, alkyl cyanoacetates and thiourea in the presence of piperidine in reflux condition provides a direct route to piperidinium 6-aryl-5-cyano 2-thiopyrimidonate salts in good yields. These reactions were also carried out under microwave irradiation. The yields of products under the microwave condition were better as compared to the reflux media. The acidification of these ionic forms resulted in the formation of 6-aryl-5-cyano-2-thiopyrimidone derivatives. The X-ray structures of the ionic forms (4, 5, and 7) show that there are anionic thiopyrimidinone skeletons hydrogen bridged with piperidinium cations.

[source] Catalysis by Ionic Liquids: Significant Rate Acceleration with the Use of [pmIm]Br in the Three-Component Synthesis of DithiocarbamatesEUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 3 2008Brindaban C. Ranu Abstract An easily accessible neutral ionic liquid, 1-methyl-3-pentylimidazolium bromide, promoted a one-pot three-component condensation of an amine, carbon disulfide, and an activated alkene/dichloromethane/epoxide to produce the corresponding dithiocarbamates in high yields at room temperature. The reactions are very fast in ionic liquids relative to those in other reaction media. These reactions do not require any additional catalyst or solvent. The ionic liquid can be recovered and recycled for subsequent reactions. A plausible mechanism is suggested. (© Wiley-VCH Verlag GmbH & Co.

The mechanism of this three-component condensation involves the intermediate formation of an ,-aminonitrile and subsequent cyclization through nucleophilic attack of the ortho -carboxylate at the nitrile carbon.
