As is the case with all esters, the alpha protons are shifted to a higher frequency ... easy-to-use 60 and 90 MHz NMR spectrometers and upgrades to the educational and industrial markets.

NMR spectroscopy can be used to elucidate structures, quantify target compounds and enable synthesis reaction monitoring in real time. It is possible to easily integrate benchtop NMR instruments ...

This method affords a mixture of diastereoisomeric iminoboronate esters whose ratio can ... of appropriate pairs of diastereotopic protons in their 1 H NMR spectra. As no kinetic resolution ...

Firstly, the 1D proton spectra of neat samples are determined on the Spinsolve® Proton NMR spectrometer. Sample preparation is performed by pipetting around 700µL of liquid into a 5mm NMR tube. The 1D ...
