Reaction Steps

Then, 26.9 g of 2'-hydroxy-3,5-dimethoxy-4,4',6'-tris(methoxymethoxy)-3'-(3-methyl-2-butenyl)chalcone was dissolved in 400 ml of ethyl acetate, and catalytic reduction was carried out by using 5% palladium/carbon. The reaction liquid was filtered through Celite to obtain 26.7 g (yield=98.5%) of 1-[2-hydroxy-4,6-bis(methoxymethoxy)-3-isopentylphenyl]-3-(3,5-dimethoxy-4-methoxymethoxyphenyl)-1-propanone.
