Synthesis of the title compound (VI) has been achieved starting from 2'-hydroxy-4',6'-di-(methoxymethoxy)-4-methoxy-3-(γ,γ-dimethylallyl)chalcone (III).Prenylation of III with prenyl bromide in the presence of methanolic KOH affords 2'-hydroxy-4',6'-di-(methoxymethoxy)-4-methoxy-3, 3'-di-(γ,γ-dimethylallyl)chalcone (IV), which on cyclization followed by dimethoxymethylation affords VI.
