A rapid flow synthesis of oxazolines and their oxidation to the corresponding oxazoles is reported. The oxazolines are prepared at room temperature in a stereospecific manner, with inversion of stereochemistry, from β-hydroxy amides using Deoxo-Fluor®. The corresponding oxazoles can then be obtained via a packed reactor containing commercial manganese dioxide.
Effective temperatures for nine giant stars are derived from recent diameter determinations at 2.2μmwith the FLUOR beam combiner on the IOTA interferometer. A good overlap with previous studies for stars earlier than M6 is verified. The present paper extends the temperature scale of giant stars based on direct measurements to types between M6 and M8.
The reaction of phosphorothioates in DNA with 2-bromoethylammonium bromide results in S-2-aminoethyl phosphorothioates, which can rearrange to N-(2-mercaptoethyl)phosphoramidates providing a facile method for the generation of site-specific thiol labeling of DNA sequences. The applicability of this method was demonstrated by conjugation of the thiolated DNA sequence with Na-(3-maleimidylpropion...
The potential for using slow-fluor liquid scintillators to study low energy solar neutrinos and neutrinoless double beta decay ($0\ensuremath{\nu}\ensuremath{\beta}\ensuremath{\beta}$) is explored through a series of simulations. fluorescence model assumed the primary fluor has characteristics similar acenaphthene, recently used demonstrate Cherenkov separation at energies around 1 MeV [Nucl. I...
