Enantioselective Cyanoethoxycarbonylation of Isatins Promoted by a Lewis Base-Broensted Acid Cooperative Catalyst

Enantioselective Cyanoethoxycarbonylation of Isatins Promoted by a Lewis Base-Broensted Acid Cooperative Catalyst

Teaming up to make it happen: In the title reaction, the Lewis basic site of the catalyst activated ethyl cyanoformate, and the deep and flexible Broensted acidic cavity stabilized and selectively recognized the key reaction intermediate to promote asymmetric acylation (see scheme).
