catalyst has been shown to be highly effective for the hydrogenation of a wide range of α-keto esters, affording either diols or hydroxy esters depending on the choice of reaction conditions. Strong base, high temperature, and pressure favor the formation of diols whilst the opposite is true for the hydroxy esters.
This invention provides novel compounds that are modulators of gamma secretase. The compounds have the formula (I) wherein R
2
is a fused bicyclic ring of the formula (II). Also disclosed are methods of modulating gamma secretase activity and methods of treating Alzheimer's disease using the compounds of formula (I).
