Thiation of 1 by LR gave the corresponding 3,5‐dithioxo derivative 2 and the trimer 3. Methylation of 1 afforded the S‐methyl derivative 4. Compound 1 was fused with 6‐bromo‐2‐phenyl‐benzo[1,3‐d]oxazin‐4‐one (5) and gave 6. Condensation of 1 with some acid derivatives 7a, 7b, 7c, 7d and/or 8a, 8b, 8c yielded thiadiazolo‐triazine derivatives 9a, 9b, 9c, 9d and 10a, 10b, 10c. Compounds 9a,9c and 10c
LR对1的硫代反应得到3,5-二硫代衍生物2和三聚体3。甲基化1可获得S-甲基衍生物4。将化合物1与6-溴-2-苯基-苯并[1,3-d]恶唑嗪-4-酮(5 )融合,得到6。1与某些酸衍生物7a,7b,7c,7d和/或8a,8b,8c缩合生成噻二唑-三嗪衍生物9a,9b,图9c,9d和10a,10b,10c。将化合物9a,9c和10c水解,得到11a,11b,11c。乙酰化14种生成的单乙酰基和二乙酰基衍生物15和16。14种苯甲酰化可提供单和二苯甲酰基衍生物17和18。14与一些芳香醛产生9a,9b,9c。反应14用苯基(异硫代和/或异硫代)氰酸酯得到脲衍生物20a,20b。的硫杂化14以P 4 s ^ 10布置21。测试了新合成的化合物作为抗微生物剂。J.杂环化学。(2011)
