Ma. Zahran et al., Synthesis of 1-substituted indole-3-carboxaldehyde related to acyclic nucleosides and their condensed pyrenyl derivatives, J CHEM R-S, (1), 2001, pp. 9-9
Indole-3-carboxaldehyde was N-alkylated to give the corresponding acyclic n
ucleosides 3a-h which were condensed with 1-pyrenamine and 1-acetylpyrene t
o give 5a,c,e-g and 7b-d,e,g, respectively. The Schiff's bases 5a and 5e wi
th 2-hydroxyethyl and methylthiomethyl N-1 substituents were found moderate
ly active against HIV-1.
