The Vilsmeier reaction for the synthesis of the 5‐formylimidazo[2,1‐b]thiazoles 7–12 bearing a p‐substituted phenyl ring in position 6 is reported. These compounds were used for the synthesis of the thiosemicarbazones 7a‐12a, tosylhydrazones 7b‐12b and 5‐hydroxymethyl derivatives 13–18 which, in turn, were used as starting materials for preparing the methylcarbamic 13a‐18a, ethylcarbamic 13b‐18b and
报道了用于合成 5-甲酰基咪唑并 [2,1-b] 噻唑 7-12 的 Vilsmeier 反应,该反应在 6 位带有对取代的苯环。这些化合物用于合成缩氨基硫腙 7a-12a、甲苯磺酰腙7b-12b 和 5-羟甲基衍生物 13-18,进而用作制备甲基氨基甲酸 13a-18a、乙基氨基甲酸 13b-18b 和乙酸的起始原料酯 13c-18c。报告了 P-388 白血病测试的初步结果。
