Abstract

New amphiphilic nucleosides 3, 5, 7, 9 and nucleobases 12, 14, with lipophilic alkynyl substituents attached to the N-heterocyclic ring were obtained in a straightforward manner by Sonoga­shira coupling of 5-iodouridine, 8-bromoadenosine and protected 8-bromoguanosine or related halonucleobases. In most cases protective groups were unnecessary.
