From [11C]CO2 to [11C]amides: a rapid one-pot synthesis via the Mitsunobu reactionElectronic supplementary information (ESI) available: Experimental details and NMR spectra. See DOI: 10.1039/c7cc01407d

A novel amide synthesis methodology is described using amines, CO 2 and Grignard reagents and Mitsunobu reagents. The method was applied to carbon-11 radiochemistry to label amides using cyclotron-produced [ 11 C]CO 2 . The synthetic utility of the one-pot labelling methodology was demonstrated by producing [ 11 C]melatonin. The incorporation of [ 11 C]CO 2 into [ 11 C]melatonin was 36% - determined by radioHPLC 2 min post [ 11 C]CO 2 delivery. Radiosynthesis of [ 11 C]amides via the Mitsunobu reaction.
