The scope of the [4 + 2] cycloadditionreactions of substituted 1,2,3-triazines, bearing noncomplementary substitution with electron-withdrawing groups at C4 and/or C6, is described. The studies define key electronic and stericeffects of substituents impacting the reactivity, mode (C4/N1 vs C5/N2), and regioselectivity of the cycloadditionreactions of 1,2,3-triazines with amidines, enamines, and
