Abstract
A series of analogues of pseudoisocytidine were synthesized via Witting reaction. We successfully raised the yields of the key-intermediates(Ⅵ ) by improving the experimental procedure, and also investigated profoundly the condensing condition of Ⅵ with some sorts of guani-dines and amidines.
