The lack of stereochemical control has been a major hurdle in synthesizing beta-nucleosides in large scale. This paper reports a study of the effects of different catalysts used in the synthesis of beta-nucleosides, The effects of time and temperature on alpha- and beta-anomers are illustrated in this paper, The yield and selectivity of the beta-nucleoside have been improved vastly at temperatures between -30 and -40 degrees C and by using SnCl4 as the catalyst.
