3-氨基-3-甲基丁-1-醇可用作医药合成中间体。
制备将46.0克(0.362摩尔)2,4,4-三甲基-5,6-二氢-1,3(4H)-恶嗪滴加到6M水溶液中,然后在室温下加入150毫升NaOH。将所得混合物加热至80℃并搅拌20小时后冷却至室温,随后用DCM(三次,每次100毫升)萃取。合并DCM层,用3×100毫升盐水洗涤,并使用MgSO4干燥。蒸发溶剂后得到3-氨基-3-甲基丁-1-醇(11.0克,产率29%),为棕色油状物。

Taking into consideration the known mechanism of the drug action of cyclophosphamide (1), several analogs and related compounds 5, 6, 7, 9, 11, 12 and 27 were synthesized, and tested against lymphocytic leukemia P 388 in mice.
Moderate to high activity was found with 5 (T/C × 100 = 243 at a dose of 300 mg/kg), 7 (T/C × 100 = 155 at a dose of 55 mg/kg). None of these compounds was found to be more active than 1 (T/C × 100 = 339 at a dose of 65 mg/kg). Although the essential position C 4 for the enzymatic activation is completely blocked in 5, the compound possesses a high degree of activity. This result justifies a reevaluation of the proposed mechanism of drug action of 1 and its analogs.
