The synthesis of a new trifluoromethyl oxetane was developed using a Corey–Chaykovsky epoxidation/ring‐expansion reaction of trifluoromethyl ketones. The reaction was shown to proceed under mild conditions and displays a broad substrate scope. The trifluoromethyl oxetane was also evaluated as a tert‐butyl isostere in the context of the γ‐secretase modulator (GSM) program. We demonstrate that the trifluoromethyl
Compounds and pharmaceutically acceptable salts of the compounds are disclosed, wherein the compounds have the structure of Formula (I) as defined herein. Corresponding pharmaceutical compositions, methods of treatment, methods of synthesis, and intermediates are also disclosed.
