Reaction Steps
2,4'-Dihydroxy-5-carboxychalcone is prepared in substantially the same manner as in Example 8, except that 4.5 g of the fixed α-cyclodextrin prepared in Example 10 is used as a catalyst instead of the fixed β-cyclodextrin. The recovery of the catalyst, the yield of and the selectivity for 2,4-dihydroxy-5-carboxychalcone are 100%, 53% on molar basis and 93%, respectively.
