Abstract
An effective, regioselective, and novel strategy to the access of 2,4,6-trisubstituted pyrido [2,3-d]pyrimidines is developed from the corresponding 2,4,6-trihalogenopyrido[2,3-d] pyrimidine through a Suzuki-Miyaura coupling reaction involving a novel regioselective halogen discrimination.
