Abstract
The enantioselective synthesis of substituted pyrrolidines through a mild Lewis-acid catalyzed three-component coupling reaction between picolinaldehyde, amino acids, and activated olefins is reported. The reaction uses low catalyst loadings of commercially available chiral diamines and copper triflate proposed to self-assemble in conjunction with the chelating aldehydes, 4-substituted-2-picolinaldehydes or 4-methylthiazole-2-carboxaldehyde, to generate a catalyst complex. A model is provided to explain how this complex directs enantioselectivity. This work represents a significant advance in the ease, scope, and cost of producing highly substituted, enantioenriched pyrrolidines.
