Introduction

The synthesis of Eugenol derivative compounds, 4-Alil-6- (methyletanoat) -2-methoxy phenol, is a crucial process in the development of various eugenol derivative compounds with attractive properties. These compounds have the potential to be applied in various fields such as pharmacy, cosmetics, and agro-theme. In this article, we will discuss the synthesis of 4-Alil-6- (methyletanoat) -2-methoxy phenol compounds from Eugenol through three stages of reaction, namely mannich reaction, methylation, and nucleophilic substitution.

Stage 1: Mannich Reaction

The synthesis process begins with a mannich reaction between eugenol, formaldehyde 37%, and 40% dimethylamin in reflux conditions using ethanol solvents at 78 ° C for 90 minutes. This reaction produces a 4-Alil-6- compound (Diethylamino) methyl-2-methoxy phenol with a yield of 88.9%. The formation of the dimethylaminomethyl group in the structure of this compound is confirmed by the appearance of the absorption peak in the wave number 1242.16 cm-1 in the analysis of the infrared spectroscopy (IR) and the peak of the molecular ion in 221 in the analysis of mass spectroscopy (GC-MS).

The mannich reaction is a crucial step in the synthesis of 4-Alil-6- (methyletanoat) -2-methoxy phenol compounds. This reaction involves the condensation of eugenol with formaldehyde and dimethylamin to form a new compound with a dimethylaminomethyl group. The yield of this reaction is high, indicating that the reaction conditions are optimal.

Stage 2: Methylation

In the second stage, the compound 4-Alil-6- (Diethylamino) methyl-2-methoxy phenol is reacted with methyl iodide in an ethanol solvent. This reaction produces compounds 6-[(n-iodo-n-methyl-n-methyl-n-methylmino) -4-alil-2-methoxy phenol, which is a quarter ammonium salt. Characteristics of quarter ammonium salt are shown by the appearance of uptake peaks in wave numbers 1481.33 cm-1 in the analysis of infrared spectroscopy (IR) and chemical shifts of protons at Δ = 3.1 ppm (Singlet peak) which indicates the presence of clusters +N- (CH3) 3 in the NMR spectrum.

The methylation reaction is a crucial step in the synthesis of 4-Alil-6- (methyletanoat) -2-methoxy phenol compounds. This reaction involves the reaction of the compound 4-Alil-6- (Diethylamino) methyl-2-methoxy phenol with methyl iodide to form a quarter ammonium salt. The yield of this reaction is moderate, indicating that the reaction conditions are optimal.

Stage 3: Nucleophilic Substitution

The final stage involves the nucleophilic substitution reaction between compounds 6-[(n-iodo-n-methyl-n-methyl-methylmino) -4-alil-2-methoxy phenol with sodium acetate. The reaction was carried out in a reflux condition using a water solvent at 100 ° C for 5 hours and produced a target compound, 4-Alil-6- (methyletanoat) -2-methoxi phenol with a yield of 34.74%. The formation of the methyletanoate group (ester) is confirmed by the appearance of the absorption peak on the wave number 1759.08 cm-1 in the analysis of the infrared spectroscopy (IR) and the chemical shift in proton at Δ = 2.3 ppm (the peak of the singlet) which shows the presence of the H3C-Co- group In the NMR spectrum.

The nucleophilic substitution reaction is a crucial step in the synthesis of 4-Alil-6- (methyletanoat) -2-methoxy phenol compounds. This reaction involves the reaction of compounds 6-[(n-iodo-n-methyl-n-methyl-methylmino) -4-alil-2-methoxy phenol with sodium acetate to form a target compound with a methyletanoate group. The yield of this reaction is moderate, indicating that the reaction conditions are optimal.

Analysis and Conclusion

The synthesis of 4-Alil-6- (methyletanoat) -2-methoxy phenol compounds from Eugenol through the three stages of reaction described above shows an effective and controlled method for modifying the structure of eugenol. The formation of the dimethylaminomethyl group, ammonium quarter salt, and finally the methyletanoate group in the structure of eugenol gives a clear picture of how chemical reactions can be used to manipulate molecular structure and produce derivative compounds with different properties and functions. This process has the potential to produce various eugenol derivative compounds with attractive properties, for example as antioxidants, antibacterial, or antifungal, which has the potential to be applied in various fields such as pharmacy, cosmetics, and agro-theme.

The Importance of Using the Spectroscopic Method

Spectroscopy analysis such as infrared spectroscopy (IR) and core magnetic resonance (NMR) are important tools in identifying and characterizing organic compounds. The use of this method in 4-Alil-6- (methyletanoat) synthesis -2-methoxy phenol provides valuable information about changes in molecular structure at each stage of reaction. The peak of the uptake of characteristics that arise in the IR and NMR spectrum shows changes in structure and the existence of the desired specific functional group.

Development Potential
