Synthesis of 4-Alil-6- Compounds (Methoxymethyl) -2-methoxy phenol from Eugenol: Mannich, Methylation, and Substitution Reaction Process

Introduction

Eugenol derivative compounds, namely 4-Alil-6- (methoxymethyl) -2-methoxy phenol, have been successfully synthesized through a series of chemical processes including mannich reactions, methylation, and nucleophilic substitution. The synthesis process begins with a mannich reaction, where eugenol, formaldehyde (37%), and dimethylamine (40%) are mixed in ethanol solvents under the reflux condition at 78 ° C for 90 minutes. The result of this reaction is a 4-Alil-6- compound (Diethylamino) methyl-2-methoxi phenol with a yield rate of 85.65%. This article aims to discuss the synthesis process of 4-Alil-6- compounds (methoxymethyl) -2-methoxy phenol from eugenol through mannich reactions followed by methylation and substitution using sodium methoxide.

Synthesis Process

The synthesis process of 4-Alil-6- compounds (methoxymethyl) -2-methoxy phenol involves several stages of reaction. The first stage is the mannich reaction, where eugenol, formaldehyde (37%), and dimethylamine (40%) are mixed in ethanol solvents under the reflux condition at 78 ° C for 90 minutes. The result of this reaction is a 4-Alil-6- compound (Diethylamino) methyl-2-methoxi phenol with a yield rate of 85.65%. The presence of dimethylaminomethyl group in the compound produced is characterized by C-n vibration in wave numbers 1234.44 cm-1 and the peak of molecular ions detected in GC-MS analysis with a value of 221.

The second stage is the methylation process, where the compound produced in the first stage is reacted with methyl iodide to introduce methyl groups in nitrogen, producing more reactive compounds for the next step. The chemical shift at Δ = 3.1 ppm indicates the presence of protons at +n- (CH3) which appears in the form of a singlet peak.

The final step in this synthesis is the reaction of nucleophilic substitution, in which 6-[(n-iodo-n-methyl-n-methylmino) methyl] -4-alil-2-methoxy phenol react at 100 ° C in reflux conditions for 5 hours. This process produces 4-Alil-6- compounds (methoxymethyl) -2-methoxy phenol with 41.35% yield. Supporting this analysis can be seen in the vibration of asymmetric C-O-C ether with the absorption peak at the wave number 848.68 cm-1, and chemical shift at Δ = 3.3 ppm which shows the protons at H3C-O-CH2 with the peak of singlets.

Analysis and Explanation of the Synthesis Process

The synthesis process of 4-Alil-6- compounds (methoxymethyl) -2-methoxy phenol is an interesting example in organic chemistry, mainly because it involves several different stages of reaction. Mannich's reaction is an important first step, because it allows the introduction of amine groups in the structure of compounds, which will affect the chemical and physical properties of the final product. Through this reaction, we can use eugenol, which is a natural compound that is found in many clove oil and other natural ingredients.

Methylation as the second stage aims to increase the stability of compounds and modify its properties, such as increasing solubility and reactivity. This process also shows how methyl iodide as a methylation agent can function to introduce methyl groups in nitrogen, producing more reactive compounds for the next step.

The last step, nucleophilic substitution, is the key to getting the desired final product. This reaction utilizes sodium methoxide as a nucleophile to replace the iodo group with metoximethyl groups, produces compounds that have potential applications in the pharmaceutical and biochemical fields.

Conclusion

In this whole synthesis, each step is not only important to produce the desired compound, but also gives a deeper understanding of the mechanism of chemical reactions, the properties of compounds, and the potential for the application of the products produced. Through this research, we can see that the synthesis of complex compounds not only requires the right reagent selection, but also a deep understanding of the reactions involved.

Future Directions

The synthesis of 4-Alil-6- compounds (methoxymethyl) -2-methoxy phenol from eugenol through mannich reactions followed by methylation and substitution using sodium methoxide has potential applications in the pharmaceutical and biochemical fields. Future research directions include the optimization of the synthesis process, the exploration of new reagents and conditions, and the investigation of the properties and applications of the final product.
