실험 절차
Using vanillyl alcohol (1.70 g, 11.0 mmol) instead of homovanillyl alcohol, and n-decanoic acid (1.72 g, 10 mmol) instead of 8-methylnonanoic acid in Example 1, similar reaction was performed. The residue was purified by PTLC to find that the yield of the obtained vanillyl decanoate was 1.33 g (4.31 mmol, 43.1%), and vanillyl decanoate was decomposed (i.e., unstabilized) by the contact with silica gel. In contrast, the isolation yield of homovanillyl 8-methylnonanoate obtained by similar operation was 93.2% as mentioned above, suggesting that homovanillyl 8-methylnonanoate is far stabler than vanillyl decanoate even upon contact with silica gel. In addition, since good isolation yields were obtained in Examples 2 to 23 where isolation and purification were similarly performed by PTLC, it is clear that the compound of the present invention is superior to capsinoids in the stability.
