= 9.0, 9.0 Hz, H-4'') all showed axial-axial coupling constants, which suggested that all substituents in this hexose are in equatorial positions. Therefore, the sugar was identified as glucose. In butanoyl substituted phloroglucinols, the glucose unit can be attached to either 1-OH (3-OH) or 5-OH positions. If the substitution is made at 5-OH, it leads to a symmetric benzene nucleus, which show only four aromatic
