Efficient synthesis of various acycloalkenyl derivatives of pyrimidine using cross-metathesis and Pd(0) methodologies
摘要:
Novel acyclonucleosides (9a-d, 10a-d, 18a,b and 19a,b) have been prepared using Pd(0) and cross-metathesis methodologies. The allylic N-alkylation under Tsuji-Trost conditions was used to introduce the nucleobase, while the Suzuki-Miyaura reaction afforded C-5 substituted uracil analogues. The cross-metathesis performed with a ruthenium catalyst was used to provide new acycloalkenyl nucleosides. The antiviral activities of all final compounds have been evaluated. (C) 2004 Elsevier Ltd.

The synthesis of novel acyclic nucleosides in the 5-alkynyl and 6-alkylfuro[2,3-d]pyrimidine series is described. These compounds were evaluated against HIV and HSV in order to determine their spectrum of antiviral activity. Their cytotoxicities against PBM, CEM and VERO cells were also determined. Compounds 21d and 24b displayed moderate EC50s of 2.7 and 4.9 microM, respectively, against HIV-1 and
