NaH (60 % in mineral oil, 53 mg, 1.31 mmol) was added to a solution of 16 a (300 mg, 1.30 mmol) in anhydrous DMF (5 mL) at 0 °C, followed by a concentrated solution of sulfamoyl chloride (∼0.69 m in toluene, ∼5 equiv) in one portion 15 min later after the evolution of H2 had ceased.
NaH (60 % in mineral oil, 65 mg, 1.62 mmol) was added to a solution of 17 (500 mg, 1.57 mmol) in DMF (40 mL) at room temperature cautiously followed by 1-bromopentane (0.4 mL, 3.23 mmol) 15 min later after the evolution of H2 had ceased.
NaH (60 % in mineral oil, 350 mg, 8.75 mmol) was added to a solution of 16 a (2.0 g, 8.72 mmol) in DMF (100 mL) at 0 °C, followed by benzyl bromide (1.1 mL, 9.33 mmol) 15 min later after the evolution of H2 had ceased.
NaH (60 % in mineral oil, 65 mg, 1.63 mmol) was added to a solution of 17 (500 mg, 1.57 mmol) in DMF (130 mL) at 0 °C, followed by CH3I (0.2 mL, 3.15 mmol) 15 min later after the evolution of H2 had ceased.
NaH (60 % in mineral oil, 65 mg, 1.62 mmol) was added to a solution of 17 (500 mg, 1.57 mmol) in DMF (40 mL) at room temperature cautiously followed by 1-bromo-3-phenylpropane (0.25 mL, 1.65 mmol) 15 min later after the evolution of H2 had ceased.
Later in the evolution of the Karoo Basin, flexural tectonics was supplemented by dynamic subsidence, which created additional accommodation across the entire foreland system.
That, in turn, would help scientists understand whether imbalances in the proportions of molecule handedness arise while the molecules are forming in space or later, during the evolution of life.
The other hallmarks leading to further transition to cancer may be acquired later in the evolution of the tumor.
Our data suggest that the pseudogenes did not originate from insertion of non-functional copies, but were formed later during the evolution of hexaploid wheat.
Sequence analysis indicates that pSymA, the giant plasmid devoted to nodulation and nitrogen fixation functions, was acquired later in the evolution of the host bacterium than pSymB [ 19- 21].
