Gradient-based pulse sequences for benchtop NMR spectroscopy
Journal of Magnetic Resonance, 2020 Benchtop NMR spectroscopy has been on the rise for the last decade, by bringing high-resolution NMR in environments that are not easily compatible with high-field NMR. Benchtop spectrometers are accessible, low cost and show an impressive performance in terms of sensitivity with respect to the relatively low associated magnetic field (40-100 MHz ...

Iridium-Catalyzed Silylation of Five-Membered Heteroarenes: High Sterically Derived Selectivity from a Pyridyl-Imidazoline Ligand. [PDF]
, 2020 The steric effects of substituents on five-membered rings are less pronounced than those on six-membered rings because of the difference in bond angles. Thus, the regioselectivities of reactions of five-membered heteroarenes that occur with selectivities

Benchtop NMR analysis of piperazine‐based drugs hyperpolarised by SABRE [PDF]
Magnetic Resonance in Chemistry, 2020 AbstractPiperazine‐based drugs, such as N‐benzylpiperazine (BZP), became attractive in the 2000s due to possessing effects similar to amphetamines. Herein, BZP, in addition to its pyridyl analogues, 2‐, 3‐, and 4‐pyridylmethylpiperidine (2‐PMP, 3‐PMP, and 4‐PMP respectively) was subjected to the hyperpolarisation technique Signal Amplification By ...
