Synthesis of Novel Caged Intramolecular Ketals of β‐C‐Glycopyranosidic Ketones

Novel caged intramolecular ketals of β‐C‐glycosidic ketones were prepared from pyranoses. The structures of the new compounds were elucidated by NMR and HRMS spectral analysis. Preliminary studies revealed that the intramolecular ketal could be used to protect 3‐ and 6‐hydroxyl groups of β‐C‐glycosidic ketones.

Keywords:

• Caged molecule
