Cyclic amidines 4 and 11 have been shown to be in N,C-tautomeric equilibrium with the corresponding ene-1,1-diamines which can be C-alkylated by methyl acrylate, leading respectively to the corresponding functionalized substituted amidines 6 (or 7) and 12.Key-words: amidine-ene-1,1-diamine tautomerism; C-alkylation; Michael-type reaction; α-alkylated cyclic amidines; methyl acrylate
