Abstract: The effect of poly[ β-(N7 adeninyl)ethyl methacrylate] on the reaction of uridine with N-( O,O'-diisopropyl)phosphoryl alanine was studied. It was found that the adenine-contained polymer nucleic acid analog acted as a template to accelerate the coupled action of uridine by phosphoryl alanine. In the presence of the nucleic acid analog, the yield of uridyl nucleotides and uridyl oligonucleotides were increased significantly. The template effect of poly[β-(N7-adeninyl)ethyl methacrylate] showed a selectivity to the coupled action of uridine but not the adenosine. In addition, since the skeleton polymethacrylate did not show any catalytic effect, the template effect of poly[ β-(N7-adeninyl)ethyl methacrylate] must the due to the adenine-bonded side chain.
