The synthesis of the hitherto unreported 3-amino-2,3-dihydro-6-phenyl-2-thioxo-4(1H)-pyrimidine 2 and 3-amino-2-methylthio-6-phenyl-4(3H)-pyrimidinone 3 is described. Reactions of hydrazonoyl halides 1 with either 2 or 3 afforded 6H-pyrimido[1,2-b][1,2,4,5]tetrazin-6-ones 6. The latter products were screened for their antifungal and antibacterial properties. The mechanism of the studied reactions is
迄今为止未报道的3-氨基-2,3-二氢-6-苯基-2-硫代氧杂4(1 H)-嘧啶2和3-氨基-2-甲硫基-6-苯基-4(3 H)的合成描述了-嘧啶酮3。酰肼基卤化物1与2或3的反应得到6 H-嘧啶基[1,2- b ] [1,2,4,5]四嗪-6-酮6。筛选了后者的产物的抗真菌和抗菌性能。讨论了所研究反应的机理。
