Abstract
The structurally complex antifungal agent posaconazole has been well characterized by conventional 1H- and 13C-NMR studies. In contrast, 15N resonance assignments have never been reported. We now wish to report the assignment of the eight 15N resonances of posaconazole using two-dimensional long-range 1H-15N GHMBCAD NMR data. The 15N resonance assignments were undertaken to facilitate the evaluation of the impact of 1H-15N heteronuclear shift correlation data in the Computer-Assisted Structure Elucidation (CASE) of complex molecular structures.
