A new general synthesis of isomeric nucleosides
Bera, Sanjib,Nair, Vasu
, p. 5813 - 5815 (2007/10/03)
An efficient new method for the synthesis of isonucleosides is described. The key step in the synthesis was the direct coupling of purine and pyrimidine bases with the cyclic sulfate of a carbohydrate intermediate. This reaction proceeded with high regiospecificity and stereospecificity.
Synthesis and antiviral studies of unsaturated analogues of isomeric dideoxynucleosides
Bera, Sanjib,Mickle, Travis,Nair, Vasu
, p. 2379 - 2395 (2007/10/03)
Novel isomeric dideoxynucleosides with unsaturation in the carbohydrate moiety have been synthesized. For example, isod4A was synthesized through a rearrangement reaction involving a cyclonucleoside. Support for the structures of both purine and pyrimidin
Synthesis of isonucleosides related to AZT and AZU
Purdy,Zintek,Nair
, p. 109 - 126 (2007/10/02)
Approaches to 1,4-anhydro-3-azido-2,3-dideoxy-2-[3,4-dihydro-2,4-dioxo-5- methyl-1(2H)-pyrimidinyl]-D-arabinitol, and the related uracil derivative, have been developed. These conceptually new, optically active analogs of AZT, derived from 1,4-anhydro-D-ribitol, are among the first examples of regioisomeric analogs of AZT.
SYNTHETIC APPROACHES TO NEW REGIOISOMERS OF AZT AND AZU
Nair, Vasu,Purdy, David F.
, p. 421 - 425 (2007/10/02)
Approaches to 1,4-anhydro-3-α-azido-2,3-dideoxy-2-β--D-arabinitol and 1,4-anhydro-3-α-azido-2,3-dideoxy-2-β--D-arabinitol, conceptually new hydrolytically stable, optically active analogs of 3'-α-azido-3'-deoxythymidine (AZT) have been developed.These are among the first examples of regioisomeric analogs of AZT.The key synthetic steps and key intermediates are described.The generality aspects of the approaches are addressed.
