Disclosed are novel compounds of the formula (I): or a pharmaceutically acceptable salt or solvate thereof, wherein R1, R2, R3, n and X are as defined in the specification. Also disclosed are pharmaceutical compositions comprising the compounds of formula (I). Also disclosed are methods of treating cognitive or neurodegenerative diseases such as Alzheimer's disease. Also disclosed are methods of treating a cognitive or neurodegenerative disease comprising administering to a patient I need of such treatment a combination of at least one compound of formula (I) and at least one compound selected from the group consisting of -secretase inhibitors other than those of formula (I), HMG-CoA reductase inhibitors, gamma-secretase inhibitors, non-steroidal anti-inflammatory agents, N-methyl-D-aspartate receptor antagonists, cholinesterase inhibitors and anti-amyloid antibodies.
Lewisacid-promoted intramolecular reactions of alkenyl ethenetricarboxylates and the corresponding amides have been examined. Reaction of allyl ethenetricarboxylates and the amides with Lewis acids (1–2 equiv) such as TiCl4, TiBr4, AlCl3, and AlBr3 gave 3,4-trans-halogenomethyl 2-oxotetrahydrofuran and pyrrolidine derivatives stereoselectively in high yields. The stereochemistries were determined

7-Aryl-6,7-dihydroimidazoimidazoles represent a novel series of high-affinitycorticotropin-releasing factor 1 receptorantagonists. Here, we report their synthesis and SAR as well as behavioral activity of two exemplary compounds, 7b and 7k, in a mouse canopy model of anxiety.
3]-sigmatropic rearrangement of quaternary allylic ammonium ylides via in situ activation of tertiary allylicamines with arynes under mild conditions. Using 2-(trimethylsilyl)aryl triflates as aryne precursors, a range of tertiary allylicamines bearing electron-withdrawing groups underwent [2,3]-sigmatropic rearrangement to furnish structurally diverse homoallylic amines in moderate to good yields. The reaction

8-Aryl-1,3a,7,8-tetraaza-cyclopenta[a]indenes represent a novel series of high-affinitycorticotropin-releasing factor-1 receptor (CRF1R) antagonists. Herein we report the synthesis and SAR around the tricyclic core and the anxiolytic activity of an orally dosed exemplary compound 9d (K(i)=8.0 nM) in a mouse canopy model.
