thoxy)-3-methylbutyn-1-yl)-2′-deoxyuridine was effectively synthesized in four easy steps. Its reactivity toward a range of cyclic oxonium adducts of closo-dodecaborate and cobalt-bis-dicarbollide boron clusters was studied. The cleavage reactions of cluster oxonium rings by the N,N-dimethylamino group of the modified nucleoside led to 5-ethynyl-2′-deoxyuridine conjugates with [B12H12]2− and [Co(C2B9H11)2]−
