A series of different amino acid-bearing thieno[2,3-d]pyrimidine moiety was synthesized via green chemistry aspects incorporating water as a solvent to give 2a–f, which were then acidified to attain the target compounds 3–9. Moreover, a tricyclic imidazothienopyrimidine of the glycine derivati...

A series of novel 2-hydroxyphenyl substituted aminoacetamides was designed by molecular hybridization of the aminoacetamide scaffold and 2-hydroxyphenyl motif. The target compounds were synthesized and their fungicidal activities were evaluated. Some of the target compounds showed excellent anti...

Regiospecific and diastereoselective aldol type reaction of chiral N-sulfinyl metalloenamines with α,β-unsaturated trifluoromethyl ketones was reported, which affords the corresponding tertiary trifluoromethyl allylic carbinols in high yields with good diastereoselectivities (dr up to 90:10). ...

The asymmetric synthesis of trifluoromethyl-piperidine-based γ-aminoacids and of indolizidines bearing a trifluoromethyl group is reported. These rarely described compounds are prepared in a highly enantio-enriched form employing as key step an intramolecular Mannich type process, involving an ...

Ketones and imines bearing a 2-(trifluoromethyl)allylic moiety successfully underwent nucleophilic 5-endo-trig cyclization via their metal enolates and enamides. O- or N-Cyclization proceeded exclusively in each case to afford the corresponding five-membered heterocycles with both exo-difluorome...

A series of 1-trifluoromethyl substituted indanes and indenes bearing aryl groups in positions 1 and/or 3 of the indane core have been synthesized mainly by electrophilic cyclization and arylation of the corresponding trifluoromethylated allyl and propargyl alcohols. The distinctly lipophilic co...

The spectroscopic properties of a new series of fatty acid analogs in which a dipyrrometheneboron difluoride fluorophore forms a segment of the acyl methylene chain are presented and their characteristics as fluorescent membrane probes are examined. When incorporated as a low mole fraction compo...

The electrochemical reduction of two meso-substituted dipyrrometheneboron difluorides, BODIPYs, 8-(thiophen-2-yl)-dipyrrometheneboron difluoride and 8-(phenyl)-dipyrrometheneboron difluoride, was studied in acetonitrile. Both compounds underwent two consecutive electron transfers to produce the ...

We present a film composed by bromocresol green (BCG) dye and resin mixed with isopropyl alcohol as photosensitive emulsion. In this film, we have recorded phase gratings with the emission line λ = 457 nm of an argon laser. The characterization of this film indicates us a diffraction efficiency...

In this study, high surface area semiconductors, non porous and porous titanium–niobium oxides derived from KTiNbO5 were synthesized, characterized and developed for their utility as photocatalysts for decontamination with sunlight. These materials were then used in the photocatalytic degradati...

An innovative gas sensor based on Förster Resonance Energy Transfer (FRET) has been developed. It comprises the optimization of thin blend films composed of a conjugated semiconducting polymer (host) and a conveniently chosen pH indicator dye (guest) as sensing agent for acid vapors. Spectroscop...

Photocatalytic activity of CuS incorporated into an Iranian clinoptilolite (CuS-Cp) was studied for decolorization of a mixture of Methyl Orange and Bromocresol Green under sunlight irradiation. All samples were characterized by XRD, FTIR, DRS and TG/DTG techniques. The effect of some key experi...

In this study, we applied the solution scanometric method as a new, simple, fast and inexpensive method for estimating the acidity constants of neutral red (NR) and bromocresol green (BCG) indicators in pure water and an ionic strength of 0.1 mol L−1 (KNO3).The method is based on scanning cells ...

In the present work, levocetirizine dihydrochloride (LEV) was found to interact with bromocresol green (BCG) via ion–pair formation. UV–vis and FTIR spectroscopy were used to validate the data obtained from quantum mechanical calculations (QMC). The electrostatic potential maps show that the r...
