Thiophospholipid compound and production method thereof
-
Paragraph 0039-0044, (2019/10/29)
The invention discloses a thiophospholipid compound and a production method thereof. The production method of the sulfurphospholipid compound comprises the following production steps of (1) dissolving10-12 mmol of 1-n-olefin and 10 mmol of 1-mercapto-n-alkanoic acid in a solvent dichloromethane, adding 0.05-0.5 mmol of 2,2,-dimethoxy-2-phenylacetophenone to initiate a click reaction, and after the reaction is completed, conducting separation and purification by means of silica gel column chromatography to obtain thioalkanoic acid; and (2) dissolving the thioalkanoic acid product in dichloromethane, adding N,N'-carbonyldiimidazole for activation for 0.5-4 hours, adding a mixed dimethylsulfoxide solution of 1,8-diazabicyclo[5.4.0]undec-7-ene and glycerophosphoryl choline, and after a reaction is completed, conducting separation and purification to obtain a white solid product thioalkanoic acid glycerophosphoryl choline. The structure of the provided thiophospholipid compound contains thioether bonds which are easy to oxidize, so that the thiophospholipid compound is subjected to fast oxidation modification in an oxidant, and has better hydrophilicity.

S-Alkylthiocarboxylic acids and their potassium salts were prepared by photoaddition of α-olefins (C10, C12, and C14) with mercapto carboxylic acids such as thiomalic acid, triopropionic acid, and thioglycolic acid.The physicochemical solution properties and thermal stabilities for three series of thiosurfactants were evaluated.S-Alkylthiocarboxylic acids that contain bridged S-bonds provide excellent thermally stable surfactants, and their alkaline salts exhibit good surface activity.KEY WORDS: α-Olefin, mercapto carboxylic acid, photoaddition, S-alkylthiocarboxylic acid, S-alkylthioglycolic acid, S-alkylthiomalic acid, S-alkylthiopropionic acid, surface activity, thermal stability.

The present invention relates to thioesters having the structural formula: STR1 wherein Rx is selected from the group of formulae consisting of: STR2 R1, R2 and R3 are independently selected from the group of radicals consisting of hydrogen or methyl; R4 and R5 are independently selected from the group of radicals consisting of hydrogen, alkyls having 1 to 18 carbon atoms, aryls having 6 to 10 carbon atoms, aralkyls having 7 to 9 carbon atoms, and radicals of the formula: STR3 and R6 is selected from the group of radials consisting of alkyls having 1 to 24 carbon atoms, aryls having 6 to 12 carbon atoms and aralkyls having 7 to 12 carbon atoms. These thioesters are particularly useful as a synergist for conventional phenolic and amine antioxidants.
