Reaction of 3,4,5,6-tetrahydro-2-pyrimidinethiol, prepared by cyclocondensation reaction of 1,3-diamino propane 1 and carbon disulfide, with ethyl chloroacetate and substituted aromatic aldehydes in the presence of sodium acetate and acetic acid gave 2-[(Z)-1-(aryl)]-6,7-dihydro-2H-isothiazolo[2,3-a]pyrimidine-3(5H)-one derivatives 3(a-j) in good yields. 1H-NMR spectroscopy, and elemental analy...
Using a synthetic antifoulant is an alternative technique to using natural for its economical and large-scale production characteristics. In this study, we synthesized allyl 3-oxzo[d]isothiazole-2(3H)-carboxylate (BIT-C) series of other heterocyclic compounds, including triazole, pyridine, thiazole derivatives. These monomers were used prepare new acrylic polymers by grafting them onto the side...
This work presents a systematic investigation of the electronic and conformational properties of five new fluorescent nucleobases belonging to the alphabet based on the isothiazole[4,3-d]pyrimidine molecule, very recently synthesized. This is of particular importance in the characterization of the main electronic aspects of these fluorescent nucleosides. The solvent effects of 1,4-dioxane and w...
