Frigid cats: The power of conformationally stabilized catalysts is demonstrated. By taking appropriate advantage of fluorine insertion (see scheme), purely conformational catalyst design led to a notable improvement in enantioselectivities from around 70 % to 91-98.5 % ee. The other advantage of this approach is the better understanding of the origin of the stereoselectivity in the given catalytic system.
