, respectively (Scheme 1, 4) followed by oxidation afforded 3,6-bis(methylthio)- and 3,6-bis[[(3,4-dichlorophenyl)methyl]thio]-1,2,4,5-tetrazines (6, 15). The reaction of 15 with amines provided the 6-[(arylmethyl)thio]-1,2,4,5-tetrazin-3-amines (16) while sequential displacement of both methylthio groups in 6 afforded the tetrazine-diamines 8 and 10. Hydrolysis of N,N-dimethyl-6-(methylthio)-1,2,4
将四氢-1,2,4,5-四嗪-3,6-二硫酮分别与碘甲烷和1,2-二氯-4-(氯甲基)苯烷基化(方案1、4),然后氧化得到3,6-双(甲硫基) -和3,6-双[[(3,4-二氯苯基)甲基]硫代] -1,2,4,5-四嗪(6,15)。15与胺的反应提供了6-[((芳基甲基)硫代]] 1,2,4,5-四嗪-3-胺(16),同时依次置换了6中的两个甲硫基得到了四嗪-二胺8和10。用氢氧化钾水解N,N-二甲基-6-(甲硫基)-1,2,4,5-四嗪-3-胺(11)得到四嗪-3-醇(12),将其氯化,然后用4-氯苯硫醇处理,得到13。目标6-取代的1,2,4,5-四嗪-3-胺显示出微不足道的抗疟活性。
