As shown by NMR spectroscopy, the reaction of 3-aminopropionamide oxime (9) with benzaldehyde or benzaldehyde derivatives 2a ~ d substituted with electron-attracting substituents affords products which exist as an equilibrium mixture of tautomers involving the open-chain 3-@enzylidenearnino)propiona
