, together with the atoms to which they are bound, can form a fused cycloalkyl or fused heterocycloalkyl ring. The cycloalkyl ring or the heterocycloalkyl ring can be optionally substituted with one or more substitutents. One or more compounds of formula (I), or formulations comprising such compounds, may be useful, e.g. in treating Alzheimer's Disease.

Disclosed are novel gamma secretase inhibitors of the formula. Also disclosed are methods of inhibiting gamma-secretase, methods of treating neurodegenerative diseases, and methods of treating Alzheimer's Disease. Also disclosed are processes for preparing alkenes in one reaction step using a mixture of an aldehyde (or ketone) and an alkyl substituted with two electron withdrawing groups, and reacting the mixture with: (a) a sulfonyl halide (e.g., a sulfonyl chloride) and a basic tertiary amine, or, (b) a sulfonyl anhydride and a basic amine, or (c) an aryl-C(O)-halide and a basic tertiary amine, or (d) an aryl-C(O)—O—C(O)-aryl and a basic tertiary amine, or (e) an heteroaryl-C(O)-halide and a basic tertiary amine, or (f) a heteroaryl-C(O)—O—C(O)-heteroaryl and a basic tertiary amine.
