Astragalus mongolicus Bunge is used in traditional Chinese medicine and is thus cultivated in bulk. The cultivation of A. mongolicus requires a large amount of nitrogen fertilizer, increasing the planting cost of medicinal materials and polluting the env
MS2 measurements on the peptide containing a methylol on the lysine residue showed only peptide fragments with a mass increase of 12 Da instead of 30 Da, apparently because of dehydration of the methylol group (Scheme 1, reaction 2). The methylol located on a tryptophan residue could not be ...
Nevertheless, the phase analysis result clearly verifies the distinct synthetic mechanism with the usage of Li2CO3 by which thermal dehydration of NCM hydroxide precursor is preceded into the oxide phase, followed by synthetic reaction with Li2CO3 at a much higher temperature, resulting in slow ...

On the other hand, when the reaction was conducted in solution, dehydration and conjugated addition of by-products were detected (Scheme 8). The increase in the catalyst basicity also induced a shift of the mechanism. The reaction proceeded through ion pair mechanism in gel phase and by the...
The dehydration of toluene insoluble salts TbCl3·6H2O (1), DyCl3·6H2O (2) and NdCl3·6H2O (3) in their reaction with organoaluminum compounds (RnAlX3−n): i-Bu3Al, Et3Al, Et2AlCl, EtAlCl2 and the influence of (BuO)3PO (TBP) on the process were studied. In the reaction ...
If a carbocation species is deployed by PvcB, due to electron-withdrawing property of fluoride that destabilizes the carbocation, one would expect 7 to impede isocyanoacrylate formation, thus directing the reaction outcome. In contrast, if desaturation undergoes hydroxylation followed by dehydration as...
The slides were incubated for 1 min in 95% ethanol, followed by a 2 min stain in alcoholic eosin Y (Sigma-Aldrich). Dehydration was performed in 95% ethanol and absolute ethanol (3×; 1 min each), followed by incubation in xylene (3×; 1 min each). The sections were ...
