Dilyus Lutfullich Rakhmankulov,* Vladimir Viktorovich Zorin, Eugeni Valerievich Pastushenko, and Semen Solomonovich Zlotsky

*Ufa Oil Institute, Kosmonavtov Str., 1, Ufa, 450062, Russia


Information of structure and properties of free radicals generated from cyclic acetals in reactions, which take place with their participation, is given. Data of kinetics and mechanism of chain-radical liquid-phase transformations of cyclic acetals are summarized and discussed. Possibilities and perspectives of using homolytical reactions of cyclic acetals in organic synthesis are shown.

The Role of Lone Pair Interactions in the Chemistryof the Anomeric Centre of Monosaccharides

Vernon G. S. Box*

*Department of Chemistry, Mona Campus, University of the West Indies, Mona, Kingston 7, Jamaica


The interactions of the lone pair orbitals of 0-5 with the lone pair orbitals, or empty orbitals, of substituents on the anomeric carbon (C-1) are reviewed and these interactions are shown to be of great importance in the anomeric effect, the reverse anomeric effect and the reactions at the anomeric centre of monosaccharides.
