  Synthesis of various 3'-branched 2',3'-unsaturated pyrimidine nucleosides as potential anti-HIV agents

  摘要：

  A series of four new 2',3'-dideoxypyrimidine nucleosides was synthesized and their activity against HIV was evaluated. Coupling of a suitably protected 3-methylidene xylofuranose derivative 5 with thymine and uracil afforded branched nucleosides 7a and 7b. The latter was transformed into 2',3'-dideoxy-2',3'-didehydro 3'-branched nucleoside 1 by Barton deoxygenation during which an allylic rearrangement occurred. Compounds 7a and 7b were converted into the corresponding 2,2'-anhydro derivatives by an intramolecular Mitsunobu reaction. Treatment of these compounds with LiN3 in DMF afforded the branched azidonucleosides by S(N)2' reaction. Palladium-catalyzed azidation of the allylic ester 6a allowed the introduction of an azido group in a highly regio- and stereoselective manner at C-2', affording 12. The p-anisyl group employed for the protection of the primary hydroxyl of 5 was stable in acidic and basic conditions, allowing its removal only at the end of the synthesis.

  Synthesis of branched nucleosides closely related to AZT, involving SN2′ opening of anhydronucleosides.

  摘要：

  Three 2',3'-unsaturated pyrimidine nucleosides, bearing an azido-methyl group at 2' or 3' were synthesized as potential anti-HIV agents. The key step involves an SN2' opening of 2,2' or 2,3'-anhydronucleosides by azide ion.
