N-Boc-4-哌啶甲酸乙酯在常温常压下为极淡的黄色或浅黄色液体,可用作有机合成中间体。它是一种商业化的有机合成子,在乙酸乙酯、二氯甲烷和氯仿等常见有机溶剂中溶解性较好,但在水中溶解度较低。
用途N-Boc-4-哌啶甲酸乙酯是常见的有机合成中间体,主要用作分子骨架参与药物分子及生物活性分子的合成。其环上的酯基可以转化为多种活性官能团,如羟基、醛基等;而另一端的N-Boc基团则可轻易脱除Boc保护基,释放二级胺。此外,在四氢铝锂还原作用下,N-Boc还可以将Boc基团还原为甲基,进而生成相应的三级胺类化合物。
合成方法N-Boc-4-哌啶甲酸乙酯的合成通常从商业化的4-哌啶甲酸乙酯出发,通过与二碳酸二叔丁酯反应得到带有Boc保护基的产物。文献报道了一种简便的方法:将这两种物质混合并搅拌即可直接获得目标产物。另有研究指出,在外加碘及使用乙腈作溶剂的情况下,此反应过程以高产率获得了目标化合物。
