A direct and single-step procedure towards substituted pyrimidine and pyridine derivatives via Lewis acid-promoted [3+3] annulation between 3-ethoxycyclobutanones and enamines or amidines is presented. Diverse substituted pyrimidine and pyridine derivatives were obtained in good to high yields with a wide substrate scope. (Figure presented.).
