The present invention relates to novel compounds that can be employed in the diagnosis, treatment, alleviation or prevention of a group of disorders and abnormalities associated with amyloid proteins and amyloid-like proteins, such as Alzheimer's disease. Precursors for the preparation of the compounds according to the present invention are also provided.
Competition between Nucleophilic Substitution of Halogen (S<sub>N</sub>Ar) versus Substitution of Hydrogen (S<sub>N</sub>ArH)-A Mass Spectrometry and Computational Study
ylacetamide carbanions (X=H, F, Cl) has been studied using negative ion electrospray massspectrometry ((−)ESI‐MS) technique and modelled computationally. It was proven that all three anions form cyclic σH adducts, which undergo elimination of water. In the case of X=F, formation of the σF adduct, leading to SNAr reaction, was a competing process. This is the first proof that also in the gas phase
