Annulation reactions of methyl valerolactim (2) and methyl caprolactim (3) with cyclic β-aminoesters, such as 2-carbethoxymethyl piperidine derivatives (4 or 5), often gave two kinds of products apparently arising from the imine and enamine forms of 2 and 3.These chemical properties were consistent with NMR observations of lactim ethers in CD3OD solution.Keywords- lactim ethers; 2-carbethoxymethyl piperidines; imine-enamine tautomeric equilibrium; annulation; imine type product; enamine type product
