A Facile Synthesis of Pyrimidone Derivatives and Single-Crystal Characterization of Pymetrozine
摘要:
A facile and efficient synthetic methodology for the preparation of aza-pyrimidone and beno-pyrimidone derivatives is described, in which the triazinone ring and dihydroquinazolin-2(1H)-one was convenient constructed. The structures of all the newly synthesized compounds were characterized by mass, H-1 NMR, and infrared spectroscopy. In additional, the crystal of pymetrozine was obtained to find useful information such as configuration and molecular action mechanisms.

The present invention relates to liquid chromatographic chiral stationary phases (CSPs) and their preparation. The CSPs are based on carbamate-derivatized polysaccharides that are covalently bound onto inorganic oxide carriers via unique linkage chemistry. The present invention also relates to methods of obtaining the said linkages, which include derivatizing and functionalizing the polysaccharides, and also chemically bonding the functionalized carbamate-derivatized polysaccharides onto inorganic oxide carriers. The polysaccharide derivatives so obtained can be used as materials for the liquid chromatographic chiral separation of enantiomers. The preferred inorganic oxides are silica, zirconium oxide, and aluminum oxide. Cellulose and amylose are the preferred chiral polysaccharides.
