obtained in their faction as anti-bacterials, antimalarials, anti-inflammatory agents," antivirals," antipsoriatics,' antihypertensives,' antiarthritics and coccidiostats. Other significant industrial attention was also paid to the triazines as pestisides, synthetic high polymers, chemical coatings, photographic fogging agent, dyes and intermediates in platsic manufacture. As a result of their demonstrated
4-亚芳基-2-甲基恶唑啉-5-酮和4-亚芳基-2-苯基恶唑啉-5-酮与水合肼的温和处理得到相应的肉桂酰肼。这些与过量乙酸酐一起得到标题1,2,4三嗪。引言 文献中记录了 1,2,4-三嗪环系统的大量用途。作为抗菌剂、抗疟药、抗炎药、“抗病毒药”、“抗银屑病药”、“抗高血压药”、“抗关节炎药”和抗球虫药,在他们的派系中获得了令人印象深刻的结果。三嗪作为农药、合成高聚物、化学涂料、照相雾化剂、染料和塑料制造中的中间体也引起了其他重要的工业关注。由于它们在许多应用中表现出的实用性,根据光谱数据,该化合物的结构已指定为 2-乙酰基-3-甲基-6-氧代-5-(4-氟苯基亚甲基)-1//-1,2,4 三嗪烯 (3a)。3 的形成可以根据乙酸酐对 2 的伯氨基的攻击得到最好的解释,导致不稳定的中间体 4。它在酸的存在下很容易发生脱水环化 * 应联系谁(上一篇名字是P.Hanumanthu)
