Synthesis of 5,5-dimethyl-1-pyrroline-N-oxide-2-14C
摘要:
5,5-Dimethyl-1-pyrroline-N-oxide-2-C-14 arrived via coupling of 2-nitropropane with labelled acrylate instead of acrolein. The new alternate step is safer, more convenient and efficient for C-14-labelling. The radioactive spin trap has a sp. activity of 13 mCi/mmol, >98% purity, and shows no degradation after two months at -80 degrees C in neat form.
