Acyclic analogs of pyrimidine nucleosides. Synthesis of 1-(2-hydroxyethoxymethyl)- and 1-(4-hydroxybutyl)-5-amino derivatives of uracil

Novikov,Ozerov

, p. 841 - 847 (2007/10/03)

With the objective of discovering new antiviral agents based on acyclic analogs of pyrimidine nucleosides, we have synthesized 1-(2-hydroxyethoxymethyl)- and 1-(4-hydroxybutyl) derivatives of uracil having various aromatic and heterocyclic amino-containing substituents in the 5 position of the pyrimidine ring. 1999 Kluwer Academic/Plenum Publishers.
