1 ,2 seco -Nucleosides

A series of the nucleic acid bases of the racemic 2 -deoxy-2, 3 -seco-nucleosides were prepared starting with l,3-dichloro-2-propanol, which was converted to 1160 and then to 1161. The condensation of the silylated bases...

The final chapter of Volume 67 has been authored by El Sayed El Ashry (University of Alexandria, Egypt). Professor El Ashry s subject is the acyclonucleosides. Indeed, this chapter is the first of a trilogy of chapters that will appear in Volumes 67, 68, and 69. The whole subject of acyclonucleosides has been organized so that the present chapter deals with seco-nucleosides (i.e., with a single-bond disconnection). Part 2, which is planned to appear in Vol. 68, will cover dweco-nucleosides, and Part 3 (Vol. 69) will cover triseco-, tetraseco-, and penfaieco-nucleosides. These compounds are of considerable interest because of the antiviral activity of many of them.
