The invention provides a preparation method of 1,2-bis (fatty acyl)-sn-glycerol-3-phosphatidylserine. The method comprises the following steps: enabling (S)-glyceryl acetonide, bis(diisopropyl amino)(trichloroethoxy) phosphine and N-Troc-serine benzyl ester to react and oxidize to obtain 1,2-O-isopropylidene-glycerol-3-phosphoryl-N-Troc-serine benzyl ester; carrying out hydrolysis reaction on the 1,2-O-isopropylidene-glycerol-3-phosphoryl-N-Troc-serine benzyl ester to obtain 2,3-dihydroxy propyl-1-phosphoryl-N-Troc-serine benzyl ester; enabling 2,3-dihydroxypropyl-1-phosphoryl-N-Troc-serine benzyl ester and fatty acid to be subjected to a condensation reaction to obtain 1,2-difatty acyl-sn-glycerol-3-phosphoryl-N-Troc-serine benzyl ester; carrying out hydrogenation reaction on the 1,2-di-fatty acyl-sn-glycerol-3-phosphoryl-N-Troc-serine benzyl ester to obtain 1,2-di-fatty acyl-sn-glycerol-3-phosphoryl-N-Troc-serine; and carrying out a deprotection reaction on the 1,2-difatty acyl-sn-glycerol-3-phosphoryl-N-Troc-serine to obtain the 1, 2-difatty acyl-sn-glycerol-3-phosphatidylserine.

The synthesis of phosphatidyl serine containing saturated fatty acids was thoroughly studied and optimized in order to establish a protocol amenable to large-scale synthesis. The key step was a one-pot multicomponent reaction involving an O-benzyl phosphorodiamidite, protected serine and diacylglycerol, followed by in situ oxidation of the resulting phosphite. In order to replace expensive and poorly stable tetrazole, a screening of substitutes was carried out and imidazolium chloride was selected as the best suited one. Springer-Verlag 2010.

An efficient phosphite coupling protocol is described for the syntheses of the major classes of phospholipids that are derived from 1,2-O-diacyl-sn-glycerols and analogues thereof.The symmetrical diacyl glycerols 10c,d were prepared by straightforward acylation of 3-O-benzyl-sn-glycerol (7) with the appropriate carboxylic acid in the presence of dicyclohexylcarbodiimide (DCC) and 4-(dimethylamino)pyridine (DMAP).A simple method for preparing saturated and unstaturated mixed 1,2-O-diacyl-sn-glycerols was then devised that involved stepwise acylation of 7 with different alkyl carboxylic acids and debenzylation; this procedure is exemplified by the preparation of 10a,b.The 1,2-O-diacyl-sn-glycerols 10a-d were then coupled with suitably protected lipid head groups employing reactive alkyl or aryl dichlorophosphites to give intermediate phosphite triesters in high overall yields.Oxidation or sulfurization of these phosphites proceeded smoothly to give the corresponding phosphate or phosphorothioate triesters, deprotection of which then provided the phosphatidylcholines 16 and 17, the phosphatidylethanolamine 20, the phosphatidylserine 28, and the phosphatidylinositols 37 and 38.Preparation of 37 and 38 required the invention of an improved method for resolving the isopropylidene-protected D-myo-inositol derivative 33.This phosphite coupling procedure was modified to assemble phospholipids bearing polyunsaturated acyl side chains at the sn-2-position as exemplified by the preparation of the phosphatidylethanolamine 26.The one-pot phosphite coupling procedure is also applicable to the syntheses of a variety of other biologically interesting phospholipid analogues.For example, the phosphatidylinositol analogues 49-51, in which the hydroxyl group at C(2) of the inositol ring has been modified, were prepared in excellent overall yields by conjoining the 1,2-O-diacyl-sn-glycerol 10c with the protected inositol derivatives 44, 45, and 48.Phospholipid analogues that contain other replacements of the phosphate group including phosphoramidates and thiophosphates may be prepared as evidenced by the syntheses of 56 and 61 in which the sn-3 oxygen atom of the 1,2-O-diacyl-sn-glycerol moiety is replaced with an N-benzyl group or a sulfur atom, respectively.

A general chemical method for the synthesis of glycerophospholipids and their analogues via H-phosphonate intermediates has been developed.It was found that 1,2-dipalmitoylglycero-3-H-phosphonate, prepared by the reaction of 1,2-dipalmitoylglycerol with PCl3/imidazole, reacts with various hydroxylic components (choline tosylate, N-(tert-butoxycarbonyl)ethanolamine, N-(tert-butoxycarbonyl)-L-serine) in the presence of condensing agents to produce in high yield the corresponding glycero-3-H-phosphonate diesters.These can be converted into natural phospholipids via oxidation with iodine or into thio or seleno analogues by using sulfur or selenium as oxidant, respectively.
