A broadly applicable method for amide C-N and ester C-O bond formation is based on formylpyrrolidine (FPyr) as a Lewis base catalyst and trichlorotriazine (TCT) as a cost-efficient reagent for OH-group activation. The new approach is distinguished by excellent cost-efficiency, waste-balance, scalability, and high levels of functional group compatibility.
