strength were prepared as nonlinear optical chromophores. Despite a high similarity of the molecularstructures, all three materials featured unrelated non-centrosymmetric crystallization behavior. One of the compounds exhibits a remarkable packing with Z′ = 16 molecules in the asymmetric unit forming two interpenetrating subsystems.

sequence based on two‐fold quaternization followed by the key intramolecular [2+2+2] alkyne cycloaddition. The physico‐chemical properties of four new linquats were characterized by spectroscopic methods, X‐ray crystallography, and electrochemistry complemented by information obtained from DFT calculations. Electron deficient N‐heteroaromatic cations with linear extended diquat motif with high electron

The present invention is directed to benzazole compounds that inhibit β-site amyloid precursor protein-cleaving enzyme (BACE) and that may be useful in the treatment or prevention of diseases in which BACE is involved, such as Alzheimer's disease. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which BACE is involved.
