Methyl 3-Phenylpropanoate is also called methyl phenylpropanoate, methyl hydrogenated cinnamate. Esters and derivatives of esters have important uses in medicine, chemicals, fuels, etc., such as synthetic perfumes, flavoring agents, detergents, and surfactants.
Methyl 3-Phenylpropanoate is used as a pharmaceutical intermediate and also used in organic synthesis.
Preparation of Methyl 3-Phenylpropanoate
Method 1: Add 4mL of methanol, 0.3mmol of styrene, and 0.1g of 0.15wt% Ru/CeO2 catalyst to a 50mL Teflon-lined reactor, add a magnet, fill it with 0.5MPa CO, seal it, and The reaction was stirred at 180° C. for 12 hours. After the reaction, the product was characterized by mass spectrometry and quantified by gas chromatography. The product looks like this:
Method 2. Methylation reactions are not only related to biological processes, but also play an important role in the functionalization of bioactive molecules in synthetic chemistry. Traditional methylating reagents include methyl iodide, dimethyl sulfate, methyl p-toluenesulfonate, and diazomethane. Although these methylating reagents are efficient, they are usually unstable, dangerous or highly toxic. CN201811224832.6 reported that methyl trifluoroacetate was used as a green and environmentally friendly reagent to react in the presence of a base to obtain the corresponding methylated product.
Preparation of Methyl 3-Phenylpropanoate
Add phenylpropionic acid (100 mg, 0.67 mmol), DMF (4 mL), potassium tert-butoxide (224 mg, 2.0 mmol, 3eq.) into the reaction flask in turn, stir at room temperature for 5 minutes, and wait until the potassium tert-butoxide is uniform After dispersion, methyl trifluoroacetate (0.27mL, 2.7mmol, 4 eq.) was slowly injected into the reaction bottle. After 4 hours of reaction, TLC spotting showed that the raw material point disappeared, and the stirring was stopped. Extract twice with ethyl acetate and distilled water, then wash with saturated NaCl solution, combine the organic phases, dry the organic phases with anhydrous magnesium sulfate, filter to remove magnesium sulfate, remove the solvent by rotary evaporation, and purify by column chromatography to obtain colorless liquid styrene-acrylic acid Acid methyl ester (80 mg, 73% yield). HNMR (400 MHz, CDCl3) δ7.30 (d, = 7.0 Hz, 2H), 7.22 (d, = 7.8 Hz, 3H),3.70 (s, 3H), 2.98 (t, = 7.8 Hz, 2H), 2.66 (t, = 7.9 Hz, 2H); C NMR (100MHz, CDCl3) δ173.32, 140.54, 128.52, 128.29, 126.29, 51.58, 35.71, 30.97.
