HPLC-purified and lyophilized samples (ca. 1–5 mg) were dissolved in 600 µL of CD3OD (99.96 atom % D; Sigma-Aldrich) or CD3OH (99.5 atom % D; Cambridge Isotope Labs). Spectra were obtained with either a Bruker AVANCE 900 MHz narrow bore spectrometer equipped with an inverse 5 mm TCI cryogenic probe with z-axis pulsed field gradient (pfg) capability or on an Agilent VNMRS 750 MHz narrow bore magnet spectrometer equipped with a 5 mm triple resonance (1H-13C-15N) triaxial gradient probe and pulse-shaping capabilities. Samples were held at 298 K during acquisition. Standard Bruker or Varian pulse sequences were used for each of the following experiments: 1H, 1H with solvent suppression using excitation sculpting (Bruker: zgesgp), 1H-1H TOCSY (80 ms mixing time; Bruker: dipsi2esgpph), 1H-13C HSQC (multiplicity-edited; Bruker: hsqcedetgpsisp2), and 1H-1H NOESY (400 ms mixing time; Bruker: noesyesgpph; Varian: dpfgse_noesy). 2D spectra in CD3OH employed solvent suppression as per the listed pulse sequences. Spectra were recorded with Bruker TopSpin 1.3 or VNMRJ 3.2A software, and data was processed using MestReNova 8.1.1. Chemical shifts (δ, ppm) were referenced internally to the solvent peak. All NMR data are shown in Supplementary Figure 15.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
