Abstract

To improve the anti-HIV activity of 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT), a variety of its analogues were synthesized. Introduction of SR group to the C-6 position was carried out based on LDA lithiation followed by the reaction of aryl- or alkyl disulfide. An addition-elimination reaction of a 6-phenylsulfinyl derivative was used for synthesizing the analogues having OR or NHR group at the C-6 position. The C-5 modified derivatives were synthesized mainly based on LTMP lithiation of a 6-phenylthio derivative. Modification at the 2- or 4-position was also carried out. Some compounds prepared in the present study showed higher activity than HEPT.
