Research speed reading in 2021. The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 140-67-0, Name is 1-Allyl-4-methoxybenzene.

The lead compound of a new series of azabicyclic carbamates described by Astra Laboratories as ligands for the alpha7 nicotinic acetylcholine receptor subtype, namely N-(4-bromophenyl)carbamic acid quinuclidin-3-yl ester, has been labelled with carbon-11 using no-carrier-added [C-11]phosgene and the isocyanate pathway. Typically, 25-35 mCi (0.92-1.29 GBq) of the tracer was obtained within 30 min of radiosynthesis (HPLC purification included) with specific radioactivities ranging from 500 to 800 mCi/mu mol (18.5-29.6 GBq/mu mol). Biodistribution studies demonstrated a relatively good brain uptake of the compound (0.8-1.2% I.D./g tissue in various brain regions), but without preferential concentration in brain regions rich in alpha7-subtype nicotinic receptor (e.g. hippocampus, pons and colliculi). No specific binding could be demonstrated in pre-saturation studies performed with both the cold compound and nicotine. Therefore, this ligand is not suitable for further exploration in PET imaging.
