This invention relates to novel lactams having the formula (I):
to their pharmaceutical compositions and to their methods of use. These novel compounds inhibit the processing of amyloid precursor protein and, more specifically, inhibit the production of Aβ-peptide, thereby acting to prevent the formation of neurological deposits of amyloid protein. More particularly, the present invention relates to the treatment of neurological disorders related to β-amyloid production such as Alzheimer's disease and Down's Syndrome.
Formal [3+2] Cycloaddition Between in situ Formed 1,4‐Benzodiazepin‐2‐One‐Based Azomethine Ylides and Azodicarboxylic Acid Derivatives: Diastereoselective Synthesis of Spiro‐1,4‐Benzodiazepin‐2‐Ones
In the presence of PhCO2H (20 mol%), the formal [3+2] cycloaddition between in situ formed 1,4‐benzodiazepin‐2‐one‐based azomethine ylides and azodicarboxylic acid derivatives proceeded readily, thus leading to the formation of trans‐configured spiro‐1,4‐benzodiazepin‐2‐ones in up to 98% chemical yield with >20:1 dr. The relative configuration of the title compounds was unambiguously determined by
