2-isopropyl-5-methylphenyl icosanoate

Alexander Martin
The novel ester product (thymyl arachidate, or 2-isopropyl-5-methylphenyl icosanoate) formed by refluxing thymol and arachidic acid in acetonitrile with EDC.HCl and DMAP. The acid wasn't particularly soluble in the reaction mixture until heated and stirred vigorously, and the reaction solution was clear during reflux with the product falling out of solution as it cooled. Upon use of a Rotavapor with a waterbacth at 40 ÂșC to dry the product after workup, the product was a...

2-methoxyphenyl (9E,12E,15E)-octadeca-9,12,15-trienoate

Akil Hossain
Reaction of Linolenic acid and Guaiacol was carried out under reflux with EDC.HCl and DMAP as the catalyst to produce an the ester. Ester was then isolated using aqueous organic workup using Hexane as the solvent. Ester was then filtered using gravity filtration and rotary evaporator was used to remove the solvent.

4-allyl-2-methoxyphenyl 2-cyclohexylacetate spectra

Rosie Millns
Reacted eugenol and cyclohexaneacetic acid with DMAP, EDC.HCl, in acetonitrile under reflux, then extracted from hexane solvent with rotary evaporator. NMR run in CDCl3.

2-methoxyphenyl (E)-octadec-9-enoate

Seren Hewer
Reaction of guiacol (2-methoxyphenol) and elaidic acid ((E)-octadec-9-enoic acid) to produce the corresponding ester of 2-methoxyphenyl (E)-octadec-9-enoate. Refluxed at 100 degrees Celsius with a solvent of acetonitrile (boiling point of 83 degrees Celsius), EDC.HCL and dimethyl amino pyridine which produced a urea byproduct. The reaction over an hour was monitored by TLC analysis comparing presence of guaiacol in reaction mixture over time (being the limiting factor). The compound was then isolated from the solvent and...

2-methoxyphenyl docosanoate

Marzuq Khan
Non-purified esterification of 5 mmol of guaiacol and 5.5 mmol behenic acid. Reaction mixture of starting materials along with DMAP and EDC.HCL in acetonitrile refluxed at 90 degrees Celsius for an hour. Washed mixture using hydrochloric acid then sodium bicarbonate then water then brine. Dried with magnesium sulfate and filtered under gravity. Used rotary evaporator to remove solvent.

2-methoxy-4-(3-oxobutyl)phenyl 2-(p-tolyl)acetate

Wen Hui Marco Fang
Synthesis of 2-methoxy-4-(3-oxobutyl)phenyl 2-(p-tolyl)acetate from zingerone and 4-methylphenylacetic acid. The peak at 3.5-4.0ppm has an integration of 5.29 - We believe that part of this is due to the zingerone (excess phenol, impurity in this case). The phenol would also take up a few peaks in the aromatic region, 6.5-7.5ppm.

2-methoxy-4-(3-oxobutyl)phenyl 2-cyclohexylacetate

Peter Costello
Esterification reaction to form 2-methoxy-4-(3-oxobutyl)phenyl 2-cyclohexylacetate from Zingerone and Cyclohexaneacetic Acid. Reaction was performed in acetonitrile with DMAP and EDC.HCl as catalysts. The product was then extracted from the solvent using an aqueous/organic workup, leaving it dissolved in hexane, which was then removed using a rotary evaporator. The ester is an oil, which was slightly volatile at room temperature. From looking at the spectrum, the sample is fairly pure, but it might be contaminated with...

4-(3-methoxy-4-(pentadec-1-en-2-yloxy)phenyl)butan-2-one

Liya Sheen
I reacted myristic acid with zingerone in reflux to produce an ester (4-(3-methoxy-4-(pentadec-1-en-2-yloxy)phenyl)butan-2-one). The ester was purified using organic workup techniques to remove impurities and water. The ester was then extracted into hexane. The hexane was removed from the ester using a rotary evaporator.
