"WebAug 25, 2011 · Earlier experimental [5,27,28,29,31] and theoretical studies showed that the ester group is oriented anti-periplanar relative to the CF 3 group, and syn-periplanar with respect to the proton of the chiral carbon. The ester, the CF 3 groups as well as the C-H bond of the chiral carbon are coplanar which makes this part of the molecule rigid. " - Chiral carbons in cyclic compounds
