  Synthesis of purine homo-N-nucleosides modified with coumarins as free radicals scavengers^*

  摘要：

  Cross metathesis (CM) of 9-butenylpurines with 4-butenyloxycoumarin in the presence of Grubbs 2nd generation catalyst under MW irradiation resulted to conjugated compounds containing homo-N-nucleosides and coumarins. Analogous derivatives received by the CM reaction of 9-butenyl-6-piperidinylpurine with 6-or 7-butenyloxycoumarins, allyloxycoumarins or coumarinyl acrylate. These compounds were tested in vitro for their antioxidant activity and they present significant scavenging activity. The presence of a pentenyloxy moiety, the attachment position on coumarin ring as well as a purine homo-N-nucleoside group are considered as important structural features.
