with thiosemicarbazide afforded the respective thiosemicarbazones. Acetylation of the amino acetals and alkylsulfonation of the 5-amino acetal, followed by condensation with thiosemicarbazide was employed to yield amide thiosemicarbazones. The most active compounds synthesized were 3-aminopyridine-2-carboxaldehyde thiosemicarbazone and 3-amino-4-methylpyridine-2-carboxaldehyde thiosemicarbazone which
已经合成了各种取代的吡啶-2-羧甲醛硫代半氨基甲酮(12种化合物),并评估了在患有L1210白血病的小鼠中的抗肿瘤活性。用二氧化硒氧化3-硝基-2-甲基吡啶,5-硝基-2-甲基吡啶,3-硝基-2,4-二甲基吡啶和5-硝基-2,4-二甲基吡啶生成相应的吡啶-2 -羧甲醛,然后将其转化为环状乙缩醛,随后通过催化氢化将其还原为氨基和羟氨基衍生物。硝基醛和乙缩醛与硫代氨基脲的缩合得到各自的硫代氨基脲。氨基缩醛的乙酰化和5-氨基缩醛的烷基磺化,然后与硫代氨基脲一起缩合,得到酰胺基硫代氨基脲。
