The present invention relates to O-GIcNAc hydrolase (OGA) inhibitors of formula (I). The invention is also directed to pharmaceutical compositions comprising such compounds, to processes for preparing such compounds and compositions, and to the use of such compounds and compositions for the prevention and treatment of disorders in which inhibition of OGA is beneficial, such as tauopathies in particular Alzheimer's disease or progressive supranuclear palsy; and neurodegenerative diseases accompanied by a tau pathology, in particular amyotrophic lateral sclerosis or frontotemporal lobe dementia caused by C90RF72 mutations. RB is a radical selected from the group consisting of (b-1) to (b-4).

The title synthesis was achieved by the reaction of t-butoxycarbonylguanidine with 3-bromo-1,1-dimethoxypropan-2-one as a key step. Starting with 1-tert-butoxycarbonyl-2-tert-butoxycarbonylaminoimidazol-4-carbaldehyde thus obtained expeditious synthesis of oroidin, hymenidin, dispacamide and monobromodispacamide, the representative 2-aminoimidazole alkaloids, was accomplished.
