Five different 2-alkoxypropan-2-yl groups are introduced as acid-labile protecting groups for the 5’- and 3’-hydroxy groups of a 2’-deoxynucleoside. All studied protecting groups were readily introduced with good to excellent yields using the a

We have used laser-photolysis-photoionization mass spectrometry, quantum chemical calculations, and master equation simulations to investigate the kinetics of the reaction between (E/Z)-pent-3-en-2-yl (CH3-CH - CH - CH-CH3), a resonance-stabilised hy
We have performed direct kinetic measurements of thermal unimolecular reaction of (CH3)2COO in the temperature 243– 340 K and pressure 5–350 Torr ranges using time-resolved UV-absorption spectroscopy. We have utilized a new photolytic precursor,

The kinetics of the i -C 4 H 5 (buta-1,3-dien-2-yl) radical reaction with molecular oxygen has been measured over a wide temperature range (275-852 K) at low pressures (0.8-3 Torr) in direct, time-resolved experiments. The measurements were performed

A series of α- and β-5-halo-2′-deoxyuridine derivatives were prepared with high anomeric selectivity using the conventional silylbase glycosylation method and taking advantage of the 3′- O -( N -acetyl)glycyl protection group and temperature co

Two organic radical contrast agents, TEMPO-Glc and TEEPO-Glc, were synthesized and their stabilities and contrast enhancing properties were tested with in vitro NMR and MRI experiments. Owing to the glucose moieties in the prepared compounds, this st
