Abstract A series of 5-substituted 1-methyl-3-phenyl-4,5-dihydro-1,2,4-triazin-6-ones was prepared by the reaction of α-amino acid methyl esters with appropriate nitrilimines and treated with phosphorus pentasulfide to afford 5-substituted 1-methyl-3-phenyl-4,5-dihydro-1,2,4-triazin-6-thiones. When 1,2,4-triazin-6-thiones were allowed to react with nitrilimine, the novel 4,6-dimethyl-2,8-di-phenyl
摘要 α-氨基酸甲酯与适当的腈亚胺反应,制备了一系列5-取代的1-甲基-3-苯基-4,5-二氢-1,2,4-triazin-6-ones。五硫化二磷得到5-取代的1-甲基-3-苯基-4,5-二氢-1,2,4-三嗪-6-硫酮。当 1,2,4-triazin-6-thiones 与腈亚胺反应时,新的 4,6-二甲基-2,8-二苯基-10-取代-1-thia-3,4,6,7 ,9-pentaazaspiro[4.5]dec-2,7-二烯是通过元素分析和光谱数据得到并证实的。一些合成的化合物在体外测试了它们的抗微生物活性。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。图形概要
