简介在现代化工制药中,1-叔丁氧羰基哌嗪扮演着非常重要的角色,因为它是很多镇咳药、抗过敏药、抗精神病类药物、抗菌药物、多种农药等的重要基础化学原料。由于其用途广泛,需求量不断增加,所占各种药品的成本比重偏高,所以降低1-叔丁氧羰基哌嗪的工业化成本具有非常重要的工业化价值和经济价值。
用途1-叔丁氧羰基哌嗪是一种有用的有机合成化合物。
应用N-Boc-哌嗪可用于制备下游产品1-[5-(三氟甲基)-2-吡啶基]哌嗪。
用途用作有机中间体
REFERENCE
合成方法目前合成1-叔丁氧羰基哌嗪方法主要是用无水哌嗪滴加二碳酸二叔丁酯选择性反应将哌嗪一头的氮保护起来,从而使另一头的氨基去跟另外的基团反应,这样的反应方法,哌嗪的两头都会接上二碳酸二叔丁酯,提纯时必须用大量的水来洗涤。
