The synthesis of novel tetrahydrobenzazepinones 1, 2, and 3 is described, as well as an improved synthesis of 4. The palladium catalyzed arylation approach to 1, 2, and 4 allows facile entry to benzazepinones lacking electron donating substituents on the benzo ring.

Disclosed are compounds which inhibit β-amyloid peptide release and/or its synthesis, and, accordingly, have utility in treating Alzheimer's disease. Also disclosed are pharmaceutical compositions comprising a compound which inhibits β-amyloid peptide release and/or its synthesis as well as methods for treating Alzheimer's disease both prophylactically and therapeutically with such pharmaceutical compositions.
including ringexpansion, ring opening, ring contraction, and atom transmutation of aryl scaffolds. This approach enables the synthesis of a diverse array of azepinones, unsaturated amides, isoquinolines, and indenones from naphthol substrates. Its application in the synthesis of bioactive and functional molecules as well as the conversion of complex molecular skeletons underscores its broad potential applicability
