A new series of 4,5-dihydroisoxazole-5-carboxylate derivatives were synthesized via [3 + 2] cycloaddition reaction between ethyl acrylate and nitrile oxide generated in situ in presence of Chloramine-T. The synthesized derivatives were characterized by Mass, IR and NMR Spectroscopy and their mesomorphic behavior were studied using DSC and Polarising Optical Microscopy. Synthesis and characterization
通过在氯胺-T存在下丙烯酸乙酯与原位生成的一氧化氮之间的[3 + 2]环加成反应,合成了一系列新的4,5-二氢异恶唑-5-羧酸酯衍生物。合成的衍生物通过质谱,红外光谱和核磁共振谱进行了表征,并使用DSC和偏振光学显微镜研究了它们的介晶行为。 描述了几种异恶唑啉衍生物的合成,表征及其液晶性能。
