Abstract

Susceptibility to metabolism is a common issue with the tert-butyl group on compounds of medicinal interest. We demonstrate an approach of removing all the fully sp3 C-H’s from a tert-butyl group: replacing some H’s with F’s and increasing the s-character of the remaining C-H’s. This approach gave a trifluoromethylcyclopropyl group which increased metabolic stability. Trifluoromethylcyclopropyl-containing analogs had consistently higher metabolic stability in vitro and in vivo compared to their tert-butyl-containing counterparts.
