Regioselective synthesis of deuterated analogs of the neurotoxin MPTP
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.

Previous studies have established the unexpected monoamine oxidase-B (MAO-B) substrate properties of racemic 3-methyl-6-phenyl-3-aza-bicyclo[4.1.0]heptane, the 3,4-cyclopropyl analog of the achiral proneurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). The two stereocenters present in this compound provide an opportunity to examine the enantioselectivity and diastereoselectivity of the
