2,5-dioxabicyclo[2.2.2]octane ring systems in the tautomeric forms of D-lyxo-hexopyranosid-2-ulose, 1,5-anhydro-D-tagatose and D-lyxo-hexodialdo-1,5-pyranosid-2-ulose derivatives
摘要:
3,4-O-Isopropylidene derivatives of the title compounds have been prepared by new methods and found to exhibit a high preference for tautomeric forms deriving from hemiacetalization between 6-CH2OH, or 6-CH(OH)2, and 2-C=O functions.
