  摘要：

  The synthesis of the first 'metallocenonucleosides' (nucleosides containing a metallocenic moiety in their framework) of the formula Ns-C = C-Fc, Ns-CH = CH-Fc and Ns-CH2-CH2-Fc (Ns = uridine, deoxyuridine, adenosine; Fc: C5H4FeC5H5) has been conducted in the presence of palladium salt according to the following routes: i) reaction of a 5-chloromercuri-nucleoside on ethynylferrocene; ii) hydrozirconation (Schwartz' reagent) of ethynylferrocene followed by the reaction of a 5-halogeno nucleoside; iii) direct coupling between ethynylferrocene and a 5-halogeno nucleoside. The same procedures allowed the synthesis of the corresponding 'metallocenonucleobases' Nb-C = C-Fc, Nb-CH = CH-Fc and NbCH2CH2Fc (Nb = uracil, cytosine, adenine) which have also been prepared by acid solvolysis of the nucleosides precursors. The compounds obtained were purified by HPLC technique and were characterized by H-1 NMR and mass spectrometry. The cytotoxicity in vitro has been studied on L 1210 cells. Only modest activity has been observed.
