The Production Process of N-(5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)acetamide (Tamibarotene)

N-(5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)acetamide, also known as tamibarotene, is a synthetic compound that is used as a photostabilizer in various applications, including plastics, textiles, and coatings.
The production process of tamibarotene involves several steps, which can be broadly classified into the following categories: synthesis, purification, and formulation.

The synthesis of tamibarotene involves the reaction of several starting materials in the presence of suitable catalysts and conditions.
One of the most common methods for synthesizing tamibarotene involves the reaction of 2-naphthol with acetyl chloride in the presence of a Lewis acid catalyst such as aluminum chloride.
This reaction leads to the formation of a mixture of the cis and trans isomers of N-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)acetamide, which are then separated through various techniques, such as crystallization or chromatography.

Another method for synthesizing tamibarotene involves the reduction of 5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene-2-carboxylic acid, which is prepared by the reaction of naphthalene with methyl iodide in the presence of a Lewis acid catalyst.
The acid is then reduced using a reducing agent such as lithium aluminum hydride to obtain tamibarotene.

After the synthesis of tamibarotene, the compound is typically purified through various methods, such as crystallization, chromatography, and distillation.
The purified tamibarotene is then formulated into various products, such as plastics, textiles, and coatings, by incorporating it into the manufacturing process of these products.
