Description
技术领域
本发明属于有机合成领域,具体涉及一种基于H13CO2Na试剂合成13C标记的4-三氟甲基甲酸芳酯的方法及应用。
背景技术
稳定同位素标记的试剂是一种具有高附加值和高技术含量的科研用试剂,11C、13C和14C同位素是标记有机小分子的理想工具,可以在不改变其性质和活性的情况下,无痕插入稳定或放射性标记。与放射性碳同位素(11C和14C)相比,13C是一种不需要专门操作设备的稳定性同位素,具有无放射性、无环境污染、无需放射设备和防辐射措施等优势。13C同位素在合成化学、食品安全、环境科学、生命科学研究中被广泛应用。
甲酸芳酯在碱的作用下可以温和的方式释放一氧化碳分子,利用甲酸苯酯作为CO替代源,在钯催化条件下实现的羰基化反应相继被不断报道([1]Org.Lett.2012,14,3100;[2]Org. Lett.2012,14,5370;[3]Org.Lett.2014,16,186;[4]Angew.Chem.Int.Ed.2014,53,3183.)。而利用13C标记的甲酸芳酯参与反应合成带有同位素标记的产物的报道仅两例([5]Org.Biomol. Chem.2015,13,10341–10347;[6]Org.Biomol.Chem.2016,14,3047–3052.),在这一领域有很大的改进与发展的空间。
