Solvent-free and one-pot Biginelli synthesis of 3,4-dihydropyrimidin-2(1H)-ones and 3,4-dihydropyrimidin-2(1H)-thiones using ionic liquid N,N-diethyl-N-sulfoethanammonium chloride {[Et3N–SO3H]Cl} as a green catalyst.
In this work, the ionic liquid triethylamine-bonded sulfonic acid {[Et3N–SO3H]Cl}, N,N-diethyl-N-sulfoethanammonium chloride was used as a green acidic homogeneous catalyst to synthesis of 3,4-dihydropyrimidin-2(1H)-ones and 3,4-dihydropyrimidin-2(1H)-thiones as two categories of heterocycles, from aldehyde, dicarbonyl compound and urea or thiourea throughout the one-pot three components cycloc...
متن کاملEfficient synthesis and antimicrobial evaluation of some Mannich bases from 2-arylidine-1-thia-4-azaspiro[4.5]decan-3-ones
BACKGROUND Thiazolidinone, has been employed in the preparation of different important drugs required for treatment of inflammations, bacterial infections, and hypertension. Mannich bases have been shown to exhibit diverse biological activities, such as antibacterial, and antifungal activities. Spiroheterocycles including thiazolidine moiety have antimicrobial activity. RESULTS In this study,...
متن کاملSynthesis and Biological Activity of Certain Mannich Bases Derivatives from 1, 2, 4-Triazoles
Substituted 1, 2, 4- Triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. These triazoles were used for preparation of different derivatives by two different schemes. In the first scheme the Mannich bases were prepared from 5- marcapto-s triazole Quinazolines. The 5-Marcato-s-Tr...
متن کاملpreparation of 3, 4-dihydropyrimidin-2(1H)-ones using quaternary ammonium- treated clay in water
In this study, a variety of 3, 4-dihydropyrimidin-2(1H)-ones derivatives were synthesized via three-component Biginelli reaction. The quaternary ammonium- treated clay -catalyzed process proved to be simple, efficient, and environmentally friendly.
