The present invention relates to novel compounds that inhibit LRRK2 kinase activity, processes for their preparation, to compositions containing them and to their use in the treatment of or prevention of diseases characterized by LRRK2 kinase activity, for example Parkinson's disease, Alzheimer's disease and amyotrophic lateral sclerosis (ALS).
A highly enantioselective organocatalytic aza-Michael addition of 4-nitro-pyrazole to ethyl (E)-2,2-difluoro-5-oxopent-3-enoate has been developed. This reaction enabled a concise, four-step, stereoselective synthesis of highly functionalized 3,3-difluoro-4-pyrazolo-piperidine GSK3901383A, a key intermediate for the synthesis of a leucine-rich repeat kinase 2 inhibitor API.
