Application


  • Reactivity and Steric Parameters from 2D to 3D Bulky Pyridines: Increasing Steric Demand at Nitrogen with Chiral Azatriptycenes.: The research explores the reactivity and steric parameters of bulky pyridines, specifically chiral azatriptycenes, which have potential applications in asymmetric catalysis and pharmaceutical chemistry (Bensaida et al., 2024).

  • Piperidine and Pyridine Series Lead-Free Dion-Jacobson Phase Tin Perovskite Single Crystals and Their Applications for Field-Effect Transistors.: The study investigates the use of piperidine and pyridine series lead-free tin perovskite single crystals in field-effect transistors, highlighting their potential in electronic and optoelectronic applications (Liao et al., 2024).

  • Synthesis, evaluation of biological activity and SAR of new thioalkyl derivatives of pyridine.: This research focuses on the synthesis and biological activity of new thioalkyl derivatives of pyridine, providing insights into their structure-activity relationships (SAR) and potential pharmaceutical applications (Sh Dashyan et al., 2024).

We describe here a [3+3]-type condensation reaction of O-acetyl ketoximes and α,β-unsaturated aldehydes that is synergistically catalyzed by a copper(I) salt and a secondary ammonium salt (or amine). This redox-neutral reaction allows modular synthesis of a variety of substituted pyridines
