Memory of Chirality Approach to the Enantiodivergent Synthesis of Chiral Benzo[d]sultams

The memory of chirality stereodivergent synthesis of polyfluorobenzo[d]sultams has been developed. The interest of this protocol resides in the possibility of using the chirality of a starting sulfonamide single enantiomer to synthesize the target sultams in both absolute configurations, by using different base systems, under homogeneous conditions.
