A method for producing a cinnamic acid ester derivative includes reacting a cinnamic acid derivative compound represented by the formula (1), wherein the symbols are as defined in the description, with an alcohol compound represented by the formula: R6OH, wherein the symbol is as defined in the description, in the presence of a strong acid resin catalyst without using a solvent. As the cinnamic acid derivative compound, cinnamic acid, ferulic acid, and caffeic acid are preferred, and as the alcohol compound, methanol, ethanol, propanol, butanol, pentanol, hexanol, ethylene glycol, glycerol, phenethyl alcohol, and a monosaccharide are preferred.

The invention relates to (E)-cinnamate compounds and synthetic methods thereof, and medicines containing the compounds and application thereof. According to the invention, on the basis of research on the activity of various cinnamates to resistance of plant pathogenic fungi, the novel (E)-cinnamate compounds are designed and synthesized by using a strategy of combination of active structure units; and it is found that the compounds have substantial inhibitory activity to a plurality of plant diseases and have the potential to application as active components to preparation of antibacterial agents for plants.

The invention discloses a p-methoxy cinnamic acid ester preparation method and belongs to the field of organic synthesis. The p-methoxy cinnamic acid ester preparation method comprises the steps that 1, p-methoxyaniline and 60-75 wt % of sulfuric acid solution are evenly mixed, 18-25 wt % of sodium fluoborate solution is dropped into the mixed solution at the temperature from 30 DEG C to 50 DEG C; 2, acrylic ester, surfactant and catalysts are added in the solution, and the solution is evenly stirred; 18-21 wt% of sodium nitrite solution is dropped into the solution during the stirring process, all the sodium nitrite solution is dropped in the solution for 30-60 minutes, the inner temperature is controlled within the range from 30 DEG C to 45 DEG C during the dropping process, and the temperature is kept and the reaction continues for 30 to 40 minutes after the dropping is finished; 4, the temperature is increased to 50 DEG C to 60 DEG C, and the reaction is conducted for 1-1.5 hours and then the reaction is over. According to the p-methoxy cinnamic acid ester preparation method, raw materials and the catalysts are low in cost and high in using efficiency, the operation is simple and pollution is little. In addition, an ordinary diazotization reaction needs to be controlled at low temperature, and the temperature for the p-methoxy cinnamic acid ester preparation method during the dizotization process is milder, the corresponding cooling cost is saved, and the p-methoxy cinnamic acid ester preparation method has wider industrialized application prospects.

The invention relates to a fluorocyano-containing cinnamic ester liquid crystal compound and its preparing process, wherein the chemical structure of the compound is p-orthohexoxyl cinnamic acid-2-fluoro-4-hydroxybenzene nitrile ester, The preparation process comprises introducing alkoxy to 4-position of cinnamic acid (3-phenylacrylic acid) through Williamson etherification reaction, then carrying out DCC dehydration condensation, so as to make the substituted cinnamic acid and 2-fluoro-4-hydroxybenzene nitrile condense and produce needed compound. The invention also discloses the use of the compound, which can be used in not only mixed liquid crystal, but also in various LCDs.
