摘要

Abstract (R)-(−)-2-[11 C] Methoxy-Nn-propylnorapomorphine ([11 C] MNPA ([11 C] 2)) is an agonist radioligand of interest for imaging D 2/D 3 receptors in vivo. Here we sought to develop an improved radiosynthesis of this radioligand. Reference 2 was synthesized in nine steps with an overall yield of about 5%, starting from codeine. Trimethylsilyldiazomethane proved to be a practical improvement in comparison to ...
