[Synthetic studies on highly modified nucleosides directed towards creation of anti-HIV agents]

Abstract

Recent studies on the synthesis of highly modified nucleosides, especially carbocyclic nucleosides, aiming at creating anti-HIV agents have been reviewed. The review includes new methods for the synthesis of carbocyclic C-nucleosides and carbocyclic N-nucleosides including carbocyclic oxetanocin and its analogues developed in our laboratory. Among the carbocyclic nucleosides synthesized, 9-(c-4,t-5-bishydroxymethylcyclopent-2-en-r-1-yl)-9H-adenine (BCA) showed significant anti-HIV activity.
