Regioselective synthesis, stereochemical structure, spectroscopic characterization and geometry optimization of dispiro[3H-indole-3,2′-pyrrolidine-3′,3″-piperidines] (original) (raw)

The study focuses on the regioselective synthesis of novel dispiro[3H-indole-3,2′-pyrrolidine-3′,3″-piperidines] using azomethine ylides in [3 + 2]-cycloaddition reactions. The synthesized compounds were characterized using single-crystal X-ray diffraction, infrared (IR) spectroscopy, and nuclear magnetic resonance (NMR) spectroscopy. Geometry optimization of these compounds was carried out employing computational chemistry methods, highlighting their molecular electrostatic potential and geometric properties.
