Abstract: A series of new morpholinylchalcones was prepared and then used as building blocks for constructing a series of 7-morpholino-2-thioxo-2,3-dihydropyrido[2,3-d]pyrimidin-4(1H)-ones via their reaction with 6-aminothiouracil. The latter...
Abstract
Ethyl 5-acetyl-4-methyl-2-(phenylamino)thiophene-3-carboxylate (2) and there derivatives 3a-c, 4, 6a-c and 9a-f were synthesized. The structure of compound 2 was deduced by 1H-NMR, 13C-NMR, FT-IR, MS, microanalysis, and single-crystal X-ray...

The reaction of 4-nitrophenyl acetate in aqueous and ethanol solutions with imidazole as a nucleophile has been monitored spectrophotometrically. The second order rate constants of these reactions are 10 times higher in water than in...
:Abstract
Semiconductor quantum dots (QDs) are a new generation of inorganic probes with advantageous properties over traditional organic probes for biological applications. A major hurdle in the use of QDs for biology is the inability of the...
CdS nanoparticles functionalized by electroactive oligothiophenes, with narrow size distribution, have been prepared and characterized. The structure of the hybrid product was investigated by TEM, XRD, optical and FTIR spectroscopy. The modified...
