(11)C-labeled methylbenzoates [(11)C]4a-d were synthesized using Pd(0)-mediated rapid cross-coupling reactions employing [(11)C]carbon monoxide and arylboronic acid neopentyl glycol esters 3a-d under atmospheric pressure in methanol-dimethylformamide (MeOH-DMF), in radiochemical yields of 12 +/- 5-26 +/- 13% (decay-corrected based on [(11)C]O). The reaction conditions were highly favorable for the
(11)C标记的甲基苯甲酸酯[(11)C] 4a-d是在大气下使用[(11)C]一氧化碳和芳基硼酸新戊二醇酯3a-d使用Pd(0)介导的快速交叉偶联反应合成的甲醇-二甲基甲酰胺(MeOH-DMF)中的最大压力,放射化学产率为12 +/- 5-26 +/- 13%(基于[(11)C] O进行衰变校正)。该反应条件对于合成[(11)C] Am80([(11)C] 2)和[(11)C]甲基4-((5,5,8,8-四甲基-5,使用4-(5,5-二甲基-1,3,2-二氧杂硼烷-2-基)-N的6,7,8-四氢萘-2-基氨基甲酰基)苯甲酸酯([((11)C] 2-Me) -(5,5,8,8-四甲基-5,6,7,8-四氢萘-2-基)苯甲酰胺(5),二者均产生26 +/-的经衰变校正的放射化学产率(RCY) 13%,放射化学纯度> 99%,平均比放射性为44 GBq / mumol。
