Three stable and simple synthetic routes of labeled D9-Mabuterol, D9-Bambuterol, and D9-Cimbuterol were described with 98.5%, 99.7%, and 98.4% isotopic abundance and good purity. These structures and isotope-abundance were confirmed according to 1H NMR and liquid chromatography-tandem mass spectrometry.
This report presents an efficient synthesis of D6 -clenproperol and D6 -cimaterol with 99.5% and 99.7% isotopic abundance in acceptable yields and excellent chemical purities with deuterium isopropylamine as labelled precursor. Their structures and the isotope-abundance were confirmed by proton nuclear magnetic resonance and liquid chromatography-mass spectrometry.
