Efficient Synthesis of Sphingosine-1-phosphate, Ceramide-1-phosphate, Lysosphingomyelin, and Sphingomyelin

Readily available D-erythro-azidosphingosine is transformed into 3-O-silyl-protected derivative 6.Reduction of the azido group afforded 3-O-silyl-protected sphingosine 7 which was either converted into N-Fmoc-protected derivative 8 or via N-acylation into ceramide derivatives 16 and 17, respectively.Treatment of 6, 8, and 16 with bis(2-cyanoethoxy)(diisopropylamino)phosphane as monofunctional phsophitylating agent, subsequent oxidation and then removal of the protective groups furnished azidosphingosine-1-phosphate (11), sphingosine-1-phosphate (2), and ceramide-1-phosphate (4), respectively.Treatment of 8 and 17 with bis(diisopropylamino)(2-cyanoethoxy)phosphane as bifunctional phosphitylating agent and then with choline afforded after oxidation and subsequent deprotection lysosphingomyelin (3) and sphingomyelin (1), respectively in high overall yields.All final products are sterochemically pure and possess D-erythro configuration in the sphingosine moiety. - Key Words: Phosphosphingolipids, synthesis of/ Azidosphingosine/ Azidosphingosine-1-phosphate/ Phosphitylation/ Sphingosine phosphates

Synthesis and Spectral Properties of Chemically and Stereochemically Homogeneous Sphingomyelin and its Analogues

2-N-Stearoylspingosyl-1-phosphocholines of D-erythro (2S,3R) and L-threo (2S,3S) configurations and their phosphorothioyl analogues were obtained by a purely synthetic approarch using O-methyl-N,N-di-isopropylaminophosphorochloridite as the phosphitylating reagent for the formation of the phophodiester linkage.Final products were obtained pure in yields of 70-75 percent.The structure and the purity of synthesized compounds was determined using 1H, 13C, and 31P n.m.r. spectroscopy.With respect to the structure of the sphingosine long-chain base the synthetic D-erythro-SPM was found to be identical with the natural sphigomyelin from bovine brain whereas the semisynthetic N-palmitoylshingomyelin obtained via a deacylation-reacylation pathway comprises a mixture of D-erythro- and L-thero-SPM.The phosphorothioyl analogues of sphingomyelin synthesized by addition of elementar sulphur to intermediate phosphite were separated into individual diastereomers having opposite configuration at phosphorus.The absolute configurations of diastereomers at phosphorus were assigned based on the known stereospecifity of phospholipase C in the hydrolysis of phosphorothioyl analogues of phospholipids.1H N.m.r. data of synthesized compounds suggest that the configuration at C-3 of the sphingosine influences the average conformation of sphingomyelin with respect to the angle of rotation about the C(1)-C(2) bond.
