The present invention relates to O-GIcNAc hydrolase (OGA) inhibitors. 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; or alpha synucleinopathies, in particular Parkinson's disease, dementia due to Parkinson's (or neurocognitive disorder due to Parkinson's disease), dementia with Lewy bodies, multiple system atrophy, or alpha synucleinopathy caused by Gaucher's disease.

numerous bioactive molecules, and a number of methods are available for their synthesis. However, one of the simplest cyclopropanation reactions involving the intramolecular coupling of two C-H bonds in a single step has remained an elusive transformation. We demonstrate herein that this reaction is accessible using aryl bromide or triflate precursors and the 1,4-Pd shift mechanism. The use of pivalate

constants of the reaction of •OH with these systems are of the order of (2−9) × 10^9 dm^3 mol^(-1) s^(-1) at near neutral pH. The difference in the spectral features of the intermediates at near neutral pH and at higher pH (10.4) obtained with these pyrimidines are attributed to the deprotonation of the OH adducts. The G(TMPD•+) obtained at pH ∼ 6, from the electron-transfer reactions of the oxidizing
