Organocatalytic Enantioselective Michael-Type Friedel–Crafts (Hetero)arylations of Aurone-Derived Azadienes with Indolizines

Herein, we describe an enantioselective 1,4-addition of benzofuran-derived azadienes with indolizines under the catalysis of chiral phosphoric acid, which afforded new enantioenriched triarylmethane products in generally good yields (up to 90%) with high enantioselectivities (up to 98% ee). This method enabled the precise synthesis of enantioenriched triarylmethane products, which are notable for their intricate structures and the presence of two (hetero)aryls.
