Abstract

The infrared study of the solvent effect on 2-methylen-3-phenyl-3-aminocarbonyl compounds, precursors of γ-hydroxy-β-amino acids, is reported. Intramolecular hydrogen bonding between NH and ester carbonyl group is present in apolar solvents, while in polar or/and protic solvents specific solute-solvent interactions are pre-dominant. In mixtures of chloroform and cyclohexane, various equilibria are present; the composition of the solute-solvent different complexes differs as the mol% of the solvent system changes. Conformational analysis confirms the infrared findings.
