摘要：

2',3'-Di-O-mesyl-5'-O-trityl-lyxo-uridine 1 reacted with secondary amines to produce enaminonucleosides 2a-d and 3a-d. Intermediacy of 2'-ketouridine was essential for the anomerisation and enamine formation to take place. The structure of the beta-enamine was established unambiguously by analysing the hydrolysed product and that of alpha-enamine was proved with the help of crystal structure analysis.
