Abstract

The invention relates to a new preparation method of Beta-thia- Alpha -alkyl fatty acid, using alkyl halides and 2- mercapto carboxylic acid as materials. The alkyl halides and the 2- mercapto carboxylic acid are condensed, and then the Beta-thia- Alpha -alkyl fatty acid is obtained by one-step method. Beta-thia- Alpha -alkyl fatty acid with high purity is obtained by salting out, pumping filtration and recrystallization. The new preparation method of Beta-thia- Alpha -alkyl fatty acid has the advantages of little environmental pollution, high efficiency and stabilization, simple and easy operation, high purity of products, low production cost and adaptation of mass production.

Description

technical field

[0001] The present invention relates to the field of compound synthesis, more specifically, to a new method for preparing β-thia-α-alkyl fatty acids. Background technique

[0002] Long-chain thia fatty acids, also known as 3-thia-2-alkyl fatty acids, have chemical properties similar to ordinary fatty acids, but their metabolic mechanisms and effects are quite different. It was recently discovered that β-thia-α-alkyl fatty acids, also known as 3-thia-2-alkyl fatty acids, can change the fatty acid composition of phospholipids in heart and liver cells, activate the oxidation of fatty acids to reduce blood lipids, and inhibit Fatty acid and cholesterol in liver cells are synthesized, so it is more and more widely used in the field of medicine and health products.

[0003] The molecular formula of β-thia-α-alkyl fatty acids is shown in the following formula:

[0004]

[0005] where R1 is C 10 -C 30 Saturated or unsaturated alkyl or aryl, the carbon atom of ...
