Advances in Heterocyclic Chemistry

The first chapter in this volume deals with diseco-nucleosides, or analogs of nucleosides in which there are two bond disconnections. Other topics covered include the importance of cyclic sulfates as intermediaries in organic synthesis.

The first chapter in this volume, by E.S.H. El-Ashry, represents the second part of a trilogy on nucleosides he began in Volume 67. This chapter deals with diseco-nucleosides, or analogs of nucleosides in which thereare two bond disconnections. Other chapters deal with the importance of cyclic sulfates as intermediates in organic synthesis, methlypyridines and other methylazines as precursors to biand polyheterocycles, and the variety of heterocycles in nucleoside analogs in heteromonocyclic bases.
