  Rapid and efficient stereocontrolled synthesis of C-3′-ethynyl ribo and xylonucleosides by organocerium additions to 3′-ketonucleosides

  摘要：

  In order to prepare new anti-retroviral nucleoside analogues, the effect of the group at C-5' on the addition of lithium and cerium trimethylsilylacetylide on 3'-ketonucleosidcs (R(1) = H, R(1) = TBDMS) derived from adenosine and uridine was studied. The best results in respect of yield (56 to 81%) and diastereoselectivity (95:5 to >98:2) were obtained with a cerium reagent (RCcCl(2)).

  Stereoselective Preparation of 3'-C-Allyluridines and 3'-Spiro-gamma-Lactone Uridine Analogues.

  摘要：

  Grignard reactions of 3'-ketouridines 1a-c with allylmagnesium bromide and CeCl3 afforded novel 3'-C-allyluridines 2a-c and 3d-e. The diprotected 3'-keto nucleosides 1a-c afforded xylo-configurated compounds 2a-c and the 5'-unprotected 3'-keto nucleosides 1d-e afforded mixtures of xylo- and ribo-configurated compounds 2d/3d and 2e/3e. The allyluridine 2a was converted into the diol 4 by standard hydroboration and further oxidised to the 3'-spiro-gamma-lactone nucleoside 5. This compound and its deprotected analogue 6 are the first examples of a novel class of 3'-spiro nucleoside analogues.

  3′-β-Carbamoylmethylcytidine (CAMC) and its derivatives were synthesized using an intramolecular Reformatsky-type reaction promoted by SmI2 as the key step. In vitro tumor cell growth inhibitory activity was evaluated and CAMC was found to exhibit potent cytotoxicity against various human tumor cell lines. From a structure–activity relationship study it was postulated that the cytotoxic mechanism of action of CAMC did not require phosphorylation at the 5′-hydroxyl group. This study provides a novel strategy for the development of a new type of antitumor nucleoside.

  A novel efficient method for the synthesis of 3'-beta-branched uridines starting from uridine was developed, in which a SmI2-promoted intramolecular Reformatsky-type reaction was effectively used. 5'-O-(Bromoacetyl)-3'-ketouridine derivatives 12, 26, and 27 were synthesized from uridine and were subjected to an intramolecular Reformatsky-type reaction. When 12, 26, and 27 were treated with 2.0 equiv of SmI2 in THF at -78 degrees C, intramolecular carbon-carbon bond formation at the 3'-beta-position proceeded smoothly to give the corresponding 3',5'-lactones 14, 28, and 29 in high yields, respectively. Treatment of 28 with NH3/MeOH gave the 3'-beta-branched uridine derivative 32 quantitatively, which was then deprotected to give 3'-C-(carbamoylmethyl)uridine (33).
