WebThe biscatechol, (DHB L Arg L Ser) 2 (2), and monocatechol, DHB L Arg L Ser (3), compounds were also isolated and characterized. The macrolactone of ruckerbactin was not detected. The presence of L Arg in ruckerbactin makes it the diastereomer of trivanchrobactin with D Arg. The electronic circular dichroism spectra of Fe(III) … WebThe structures of ruckerbactin and the related biscatechol 2 and monocatechol 3 compounds were evaluated by NMR spectroscopy (Figures S6-S27 and Tables S1-S3). Similar resonances were observed in the NMR spectra of all three compounds, although with greater complexity in the spectra of 1 and 2 compared to 3.
