  An Improved Synthesis of 1-β-D-Arabinofuranosylcytosine 5′-Phosphate-L-1,2-diacylglycerols

  摘要：

  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.

  A new protecting group: 9-fluorenylmethoxycarbonyl (FMOC) in the synthesis of 1,2-diacylglycerols

  摘要：

  The synthesis of 1,2-L-dipalmitoyl-sn-glycerol, 1,2-L-distearoyl-sn-glycerol and 1,2-L-dioleoyl-sn-glycerol are described here using 9-fluorenylmethoxycarbonyl (FMOC) group for protection of the S-position of glycerol which can be selectively removed by Et3N treatment on the overall 60-70% yield based on 1,2-isopropylidene-sn-glycerol. Little or no acyl migration occured during deprotection and purification. (C) 1997 Elsevier Science Ireland Ltd.
