A rapid urea radiolabelling methodology has been developed. [11C]CO2 was activated by 1,8-diazabicycloundec-7-ene (DBU) in the presence of aliphatic and aromatic amines and reacted with Mitsunobu reagents to produce asymmetric 11C radiolabelled ureas in high radiochemical yields.
已开发出一种快速的尿素放射性标记方法。在脂肪族和芳香族胺的存在下,[11C]CO2通过1,8-二氮杂双环十一碳-7-烯(DBU)活化,并与Mitsunobu试剂反应,以高放射化学产率产生非对称的11C放射性标记尿素。
