  Synthesis of 1-β-d-arabinofuranosyl-cytosine 5′-phosphate-l-1,2-diacylglycerols

  摘要：

  5'-O-MMTr-cytosine arabinoside was prepared on a large scale from 5'-O-MMTr-cytidine with diphenyl carbonate via 5'-protected cytidine-2',3'-carbonate-ara-cytidine-2',2-anhydro derivative at a 67% yield. 1,2-Dipalmitoyl-sn-glycerol, 1,2-distearoyl-sn-glycerol and 1,2-dioleoyl-sn-glycerol were phosphorylated first with 2-chlorphenyl-phosphorobis-triazolide quantitatively (Welch and Chattopadhyaya, 1985. Acta Chem. Scand. B39, 47-57). This method was used in order to avoid acyl migration, then the glycerophosphate intermediates were condensed with 2',3',N-4-trileulinyl-1-beta-D-arabinofuranosylcytosine in the presence of 2-mesytilensulphonyl chloride (MSCI) and 1-methylimidazole (MeIm)-which was used in the coupling of nucleotides (Nyilas et al., 1986. Acta Chem. Scand. B40, 678-684)-in an 85-88% yield compared with the low yielding diester method of Ryu et al., 1982. J. Med. Chem. 25, 1322-1329. Deblocking was carried out in two steps with tetrabutylammonium fluoride (TBAF) and hydrazine hydrate, producing target compounds (9a, 9b, 9c) at a 50% yield. (C) 1997 Elsevier Science Ireland Ltd.

• Regiodefined synthesis and conformational properties of adenyldiyl trimers with unsymmetrical 2′–5′ and 3′–5′ internucleotide linkages

  Adenyldiyl trimers with different kinds of substitucnts on 2′–5′ and 3′–5′ phosphate linkages have been synthesized in a general, regiodefined manner. Examination of the 2D NMR spectra reveals that the trimers with adenylyl(2′–5′)adenosine linkage make a syn-anti as well as syn-syn base slack between the two adenyl bases and exist as a mixture of the two conformers.

  以一般的区域定义方式合成了在2'-5'和3'-5'磷酸键上具有不同取代基的Adenyldiyl三聚体。2D NMR谱图的检查表明，带有腺苷基（2'–5'）腺苷键的三聚体在两个腺苷酸碱基之间形成顺-反和顺-syn-顺碱基松弛，并且以两个构象异构体的混合物形式存在。

  5'-O-MMTr-cytosine arabinoside was prepared on a large scale from 5'-0-MMTr-cytidine with diphenyl carbonate via 5'-protected cytidine - 2',3'-carbonate -- aracytidine-2',2-anhydro derivative at a 67 % yield. The synthesis of 1,2-L-dipalmitoyl-sn-glycerol, 1,2-L-distearoyl-sn-glycerol and 1,2-L-dioleoyl-sn-glycerol described here using 9-fluorenylmethoxycarbonyl (FMOC) group for protection of 3-position of glycerol which can be selectively removed by Et3N treatment on the overall 60-70 % yield based on 1,2,-isopropilidene-sn-glycerol. These glycerols were phosphorylated first with 2-chlorophenyl-phosphoro-bis-triazolide quantitatively(1) in order to avoid acyl migration, then the glycerophosphate intermediates were condensed with 2',3',N-4-trileulinyl-1-beta-D-arabinofuranosylcytosine in the presence of 2-mesytilenesulphonyl chloride (MsCl) and 1-methylimidazole (MeIm)- which was used in the coupling of nucleotides(2)- in an 85-95 % yield compared with the low yielding diester method of Ryu(3.) Deblocking was carried out in two steps with tetrabutylammonium fluoride (TBAF) and hydrazine hydrate, producing target compouns (14a, 14b, 14c) at a 50 % yield.
