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.

13C-NMR analysis of the Reformatsky intermediates from t-butyl-α-bromo acetate, t-butyl-α-bromo isobutyrate and t-butyl-α-bromo propionate have evidenced C-metallated species. Their ability to act as nucleophilic reagents under mild conditions and their selectivity towards halogen-and oxygen containing electrophiles is reported.
