systems, representing a new disconnection for the synthesis of this versatile moiety. When applied to the target compound, the photochemical step could be conducted on 15 g scale using industrially relevant [Ru(bpy)3Cl2] catalyst loadings of 0.01 mol %. This transformation is part of an overall five‐step route to the antagonist that compares favorably to the current synthetic sequence and demonstrates

This invention provides thiazolylpiperazine derivatives, and N-sulfonyl heterocyclic derivatives including phenyl- and benzyl-thiazolylpiperidine derivatives, and pharmaceutically acceptable salts thereof, which are useful active ingredients for administration in a method for the treatment of an α-synucleopathy such as Parkinson's disease, diffuse Lewy body disease, traumatic brain injury, amyotrophic lateral sclerosis, Niemann-Pick disease, Hallervorden-Spatz syndrome, Down syndrome, neuroaxonal dystrophy, multiple system atrophy and Alzheimer's disease. This invention also provides methods for making such derivatives, and pharmaceutical compositions including such derivatives together with pharmaceutically acceptable excipients.
