Replacing the phenyl groups in the structure of the VMAT2 inhibitor, lobelane with either pyridyl, quinolyl or indolyl groups affords novel analogues with improved water solubility. The synthetic methodologies reported herein also underscore the paucity of hydrogenation methods that offer selectivity in the synthesis of the different classes of heteroaromatic lobelane analogues. The quinolyl group was the only replacement for the phenyl group in lobelane that retained VMAT2 inhibition.
