Reaction of a cyclic β-aminoester such as 2-ethoxycarbonylmethylpiperidine (5) with the lactim thioethers 1b and 1c gave a 10-membered cyclic diamide (7) and an 11-membered ring compound (9), respectively.On the other hand, though acyclic β-aminoesters (6) reacted with 1 to afford methyl 3-methylthiopropionate (11), N-alkyl 3-methylthiopropionamide (12), lactams (13), and amidines (14), no cyclic diamide was obtained.Keywords: - lactim thioethers; cyclic β-aminoesters; acyclic β-aminoesters; cyclic diamide; medium-ring; methyl 3-methylthiopropionate; N-alkyl 3-methylthiopionamide; amidines; lactams; β-lactmams
