Acceleration of hemiacetal cleavage through hydrogen bonding: a new synthetic catalyst with balanced conformational flexibility and preorganization
摘要:
Hemiacetal cleavage catalyst 1 was designed, synthesized, and shown to be effective in promoting glycolaldehyde dimer dissociation and tetramethylglucose mutarotation.
were systematically studied by UV-visible spectroscopy, nuclearmagneticresonance (1H-NMR) spectroscopy, liquid chromatography mass spectrometry (LC–MS) and density functional theory (DFT) calculations. The results demonstrated that the equilibrium component of GA in methanol solution is different from that in aqueous solution and that glycolaldehyde hemiacetal (GAHA) is a dominant component (>90%).
