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 β-enamine was established unambiguously by analysing the hydrolysed product and that of α-enamine was proved with the help of crystal structure analysis.
