amounts of strongly nucleophilic, non-hindered primary alkyl amines led to fast and quantitative formation of the corresponding Schiff bases. In the presence of excess amines, novel nucleosides with ring opened pyrimidine bases were formed as a result of the Michael addition of a second amine to the pre-formed imines. In the reaction of f5dU with aromatic amines, the formation of Schiff base derivatives
