实验步骤: This compound was synthesized by the method described in Kobata et al. (Biosci. Biotechnol. Biochem., 66(2), 319-327, 2002). Decanoic acid methyl ester (2.13 mL, 10.5 mmol), vanillyl alcohol (1.62 g, 10.5 mmol), molecular sheaves 4 Å (10 g), and Novozyme 435 (2.5 g) were added to acetone (50 mL) and stirred for 2 hours at room temperature. The reaction solution was filtered through cellite and the filtrate was concentrated under reduced pressure. The concentrated residue was purified by silica gel chromatography, yielding 2.25 g (7.30 mmol, 73.0 percent) of vanillyl decanoate in the form of a colorless oily substance. This compound was synthesized by the method The reaction solution was filtered through cellite the filtrate was concentrated under reduced pressure The concentrated residue was purified by silica gel chromatography

实验步骤: A solution of 0.055 mol of lithium diisopropylamide (LDA) in 100 ml tetrahydrofuran (THF) was cooled to −78° C. under an inert atmosphere, and 0.055 mol of methyl decanoate in THF was added dropwise with stirring. The mixture was allowed to warm over one hour to −20° C., then cooled again to −78° C. A solution of 1-bromo-2-butyne (0.050 mol) in THF (20 ml) was added dropwise, and the mixture allowed to warm to room temperature overnight. Aqueous 6N HCl (100 ml) was added, and the product extracted with ethyl ether, dried with anhydrous sodium sulfate, concentrated, and distilled in vacuo to provide methyl 2-(2-butynyl)decanoate as an oil. was added dropwise to warm over one hour to −20° C. to warm to room temperature overnight the product extracted with ethyl ether dried with anhydrous sodium sulfate concentrated distilled in vacuo

实验步骤: 17.5 g of decanoic acid methyl ester is dissolved in 1 l of absolute ethanol and mixed with 350 ml of hydrazine hydrate. It is refluxed for 3 hours and then stirred overnight at room temperature. The solution is concentrated by evaporation to about 300 ml and allowed to stand until the product is crystallized out. After it is filtered off and dried, 16.6 g (=94% of theory) of decanoic acid hydrazide is obtained. It is refluxed for 3 hours The solution is concentrated by evaporation to about 300 ml is crystallized out After it is filtered off dried
