Synthesis of C-Glycosides from S-Glycosyl Phosphorothioates

The proclination of the mandibular incisors was numerically smaller in the van Beek than in the Herren activator group (ILi/ML) but larger than in the activator-headgear

(2007), Pauferrol A, a novel chalcone trimer with a cyclobutane ring from Caesalpinia ferrea Mart. exhibiting DNA topoisomerase II inhibition and

For analysis, the racemic diastereomers were purified by column chromatography on silica gel (solvent: n-hexane- ethyl acetate, 4 : 1, R f = 0.42) to give the major racemic

The structure of the cluster with 64 CVE is that of a “spiked triangle” in which the triphenylphosphonioacetylide CCPPh 3 acts as a six-electron donor and the bonding mode is that of

The difference between the P–C distances to C(5) and to the phenyl carbon atoms amounts to about 10 pm, and the shorter bond lengths to the ylidic carbon atom indicate some double

Variable temperature solid emission spectra show maxima that occur at significantly lower energies than is observed in fluid solution and that shift to the red when the temperature

Whatever the explanation, it is clear that the simple change of a pyridine for a pyrazine in the trpy ligand has a dramatic effect on the energy of the solid emission..

I conducted a series of high-pressure high- temperature experiments in diamond anvil cells (DACs) and demonstrated that the predicted boron allotrope (we denoted it as ζ-B)
