Why beat about the bush? An operationally simple and mild reaction based on the direct fixation of 11CO2 with 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) has been developed for the synthesis of 11C‐labeled carbamates at 75 °C within 10 minutes in radiochemical yields above 70 % (see scheme). This strategy should be immediately useful for the construction of new radiotracers for positron emission tomography
为什么要打灌木丛?基于11 CO 2与 1,8-二氮杂双环 [5.4.0] 十一碳烯 (DBU)直接固定的操作简单且温和的反应已被开发用于在 75 °C 下合成11 C 标记的氨基甲酸酯10 分钟内,放射化学产率超过 70%(参见方案)。该策略对于构建用于正电子发射断层扫描和其他应用的新型放射性示踪剂应立即有用。
