  Practical synthesis of 4′-selenopyrimidine nucleosides using hypervalent iodine

  摘要：

  We report herein a synthesis of 4'-selenouridine 12 and 4'-selenocytidine 14, substrates for the synthesis of 4'-selenoRNA. The Pummerer-like reaction between the selenoxide 9 and a silylated uracil afforded the desired 4'-selenouridine derivative 10: however, the chemical yield of 10 was rather low. In addition, the reproducibility of this reaction was poor because of the instability of the selenoxide 9. Improvement of this Pummerer-like reaction to give 10 was achieved when the 4-selenosugar 8 was treated with TMSOTf, 2,6-lutidine and the silylated uracil in the presence of iodosylbenzene.

• Synthesis and biological evaluation of 2′-substituted-4′-selenoribofuranosyl pyrimidines as antitumor agents

  The 2′-substituted-4′-selenoribofuranosyl pyrimidines 3a–3j were synthesized from D-ribose and assayed for anticancer activity. The 2′-azido and 2′-fluoro groups with a ribo configuration were introduced by the regioselective opening of the O2,2′-anhydronucleosides with sodium azide and (HF)x-pyridine, respectively. Among the compounds tested, only 2′-fluoro derivative 3j was found to exhibit significant anticancer activity, but was much less potent than the corresponding 2′-arabino analogue 2c. This study will provide medicinal chemists with the insight into the identification of structural requirements for the anticancer activity for the developments of biologically active nucleosides.

  Stereoselective synthesis of novel 2',3'-didehydro-2',3'dideoxy-4'-selenonnucleosides (4'-seleno-d4Ns) 4a-c was accomplished via 4'-selenoribofuranosyl pyrimidines 11a-c, as key intermediates. 4'-Selenoribofuranosyl pyrimidines 11a-c were efficiently synthesized from D-ribose or D-gulonic gamma-lactone using a Pummerer-type condensation as a key step. Introduction of 2',3'-double bond was achieved by treating cyclic 2',3'-thiocarbonate with 1,3-dimethyl-2-phenyl-1,3,2-diazaphospholidine.

  The syntheses of four selenonucleosides, namely 4 '-O-selenoadenosine, -cytidine, -thymidine, and -uridine are described. Commercially available D-ribonolactone was converted to the key intermediate 1,4-anhydro-4-seleno-D-ribitol in seven steps in overall excellent yield. Oxidation of the seleno-D-ribitol with MCPBA gave a single diastereomeric selenoxide in excellent yield, which upon Pummerer reaction in the presence of silylated purine or pyrimidine bases gave stereoselectively the corresponding 4'-beta-selenonucleosides. The stereochemistry at the anomeric center was determined by means of 1D-NOE experiments. (C) 2008 Elsevier Ltd. All rights reserved.

  The first synthesis of 4'-selenonucleosides was achieved using a Pummerer-type condensation as a key step. All stereoelectronic effects shown in 4'-oxonucleosides were overwhelmed by the size of selenium and steric interactions, driving the conformation to the C2'-endol C3'-exo twist (Southern) conformation.
