A facile synthesis of [14C]enadoline [(5R)-(5α, 7α,8β)]-N-methyl-N-[7-(1-pyrrolidinyl)-1-oxaspiro[4.5] DEC-8-YL]-4-benzofuranacetamide

4-Chloromethylbenzofuran (10) was synthesized from 2,3-dimethylanisole in 7 steps. The corresponding Grignard reagent prepared from magnesium-anthracene complex reacts with 14CO2, SOCl2, and PD130812 successively to give [14C]enadoline (2), a non-peptide, selective kappa opioid receptor agonist. This method could be readily modified for the rapid, one-pot synthesis of [11C]enadoline.
4-氯甲基苯并呋喃 (10) 由 2,3-二甲基苯甲醚经 7 步合成。由镁-蒽络合物制备的相应格氏试剂依次与 14CO2、SOCl2 和 PD130812 反应,得到 [14C]enadoline (2),一种非肽、选择性 κ 阿片受体激动剂。该方法可以很容易地进行修改,以快速、一锅合成[11C]enadoline。
