Paragraph 0093; 0094; 0095, (2018/11/22)
The invention provides a diacyl phosphatidyl ethanolamine preparation method, comprises the following steps: (1) solvent and organic/inorganic alkali under the action of, the formula I compound and phosphorus reagent undergo the substitution reaction, formula a intermediate 1; (2) in the same reaction system, intermediate 1 of an organic/inorganic the presence of an alkali, with 2 - (N - [...] carbonyl amino) ethanol or N - Boc protection of the ethanolamine undergo the substitution reaction, formula b intermediate 2; (3) in the same reaction system, intermediate 2 under the action of the oxidizing agent in the oxidation reaction, the compound of formula II; (4) the formula II compound in the solvent, under the action of alkali, phospholipid base hydrolysis, formula III compound. The advantage of this invention is characterized in that: the invention only needs two-step synthesis of the target product can be obtained, and the method is easy to control conditions, after treatment is simple, less side reaction, high yield, consistent with the requirements of industrial production.
