NMR, IR, and HRMS data related to the synthesis of nitrogenated aromatics from 2-pyrones

This dataset contains the raw spectroscopic data (NMR, HRMS, and IR) for all final compounds obtained in the study entitled “Cascade Iodine-Catalyzed Synthesis of Nitrogenated Aromatics from 2-Pyrones.” The data were generated to support the structural characterization and confirmation of the synthesized compounds. All compounds were prepared following iodine-catalyzed cascade reactions starting from 2-pyrones and suitable nitrogen sources, as described in the associated study. The spectroscopic data were collected using standard analytical techniques, including nuclear magnetic resonance (NMR), high-resolution mass spectrometry (HRMS), and infrared spectroscopy (IR). The dataset consists of unprocessed (raw) spectra files, providing full experimental evidence of compound identity and purity. These data are intended to ensure transparency, reproducibility, and validation of the reported results, and may be used for comparison, reanalysis, or further methodological development by other researchers.
