Abstract A one step synthesis, using the nucleoside 7-iodo-2′-deoxytubercidin (2b) in a Pd(0)/Cu(I)-catalyzed cross coupling reaction furnished a series of 7-alkynyl-2′-deoxytubercidin derivatives. The 7-iodo-, 7-chloro- or 7-bromo 2′-deoxytubercidins 2b-d as well as certain 7-alkynyl derivatives show significant activity against several tumor cell lines, with 7-iodo-2′-deoxytubercidin (2b) as the
