Synthesis of New 1,2,3-Triazol-4-yl-quinazoline Nucleoside and Acyclonucleoside Analogues
Molecules, 2014 In this study, we describe the synthesis of 1,4-disustituted-1,2,3-triazolo-quinazoline ribonucleosides or acyclonucleosides by means of 1,3-dipolar cycloaddition between various O or N-alkylated propargyl-quinazoline and 1'-azido-2',3',5'-tri-O ...

1,3-Dipolar Cycloaddition Reactions of Substituted Benzyl Azides with Acetylenic Compounds
Molecules, 2002 We review in this article some of our work which has been published over the last fifteen years in the area of 1,3-dipolar cycloaddition reactions of substituted benzyl azides with acetylenic compounds to form the corresponding 1,2-3-triazoles.

Chemistry – A European Journal, EarlyView.This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Chemistry – A European Journal, EarlyView.Central sp3‐C substitution (─H, ─OH, ─CH3, ─OCH3, and ─OC2H5) directs supramolecular packing in tris‐HBC (hexa‐peri‐hexabenzocoronene) nanographenes, yielding diverse layered and porous architectures via modulation of intermolecular interactions. Comprehensive Raman, NMR, photophysical, and electrochemical analyses, supported by DFT/TD‐DFT calculations,

Chemistry – A European Journal, EarlyView.Two previously uncharacterized heterocyclic imines, 3‐iminooxetane and 3‐oxazoline, are generated simultaneously by irradiation of 3‐azidooxetane under matrix isolation conditions. The infrared spectra provide reference data for future gas‐phase studies and may facilitate their search in the interstellar medium.

Photocatalyst‐Free Trifluoromethylation of Indolizines Through an Electron Donor–Acceptor Complex
European Journal of Organic Chemistry, EarlyView.A new photocatalyst‐free pathway for the direct C‐3‐trifluoromethylation of indolizines and imidazo[1,2‐a]pyridines through an electron donor–acceptor (EDA) complex is studied. This regioselective reaction supports a wide range of functional groups, indicating good versatility and robustness.

Synthesis of novel phosphorylated chrysin derivatives by 1, 3-dipolar cycloaddition reaction
Phosphorus, Sulfur, and Silicon and the Related Elements, 2016 Through 1,3-dipolar cycloaddition reaction, 1,4,5-trisubstituted-1,2,3-triazole and phosphate-containing chrysin derivatives were synthesized with high yields. The target compounds were characterized by 1H, 31P, 13C NMR spectroscopy and HRMS.
