The present invention relates to cinchona-based bifunctional organocatalysts and methods for preparing chiral hemiesters using the same. More specifically, the present invention relates to methods for preparing chiral hemiesters from prochiral or meso cyclic acid anhydrides via desymmetrization, using bifunctional cinchona alkaloid catalysts comprising sulfonamide functional groups.

Inhibition of immunomodulating enzymeindoleamine2,3-dioxygenase 1 (IDO1) is considered one of the potential approaches in the fight against cancer and other diseases. Comprehensive biophysical and cellular studies have shown that quinine derivatives effectively inhibit the activity of IDO1. Mechanistic studies revealed that the potent quinine derivatives compete with heme for binding to apo-IDO1
