该中间体在本合成路线中的序号:(IV)The condensation of 2,4,6-trihydroxyacetophenone (IV) with tetraacetylbromoglucose (V) by means of NaOH in acetone-water gives tetraacetylphloracetophenone-4-O-glucoside (VI), which is condensed with 4-hydroxybenzaldehyde (VII), by means of KOH in alcohol yielding the chalcone derivative (VIII). Finally, this compound is cyclized and deprotected by a treatment with refluxing aqueous HCl.
