摘要:
1-Methyl-4-phenyl-2-pyridone has been used as starting material for the efficient and regioselective synthesis of deuterated analogues of the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). MPTP-2,2-d(2), MPTP-6,6-d(2) and MPTP-2,2,6,6-d(4) were obtained in good yield through a combination of alkaline deuterium exchange and selective LiAlH4 and LiAlD4 reduction reactions.
