A modified nucleoside analogue having the formula (I): P-S-B-L-R where: P is a 5′ triphosphate or analogue or derivative thereof; S is a substituted or unsubstituted five- or six-membered sugar, sugar analogue or acyclo sugar analogue, but excluding a dideoxy-sugar, B is a substituted or unsubstituted nitrogenous base or base analogue or derivative thereof; L is a linker group; and R is a substituted or unsubstituted metallocene moiety or substituted or unsubstituted metal complex or substituted or unsubstituted redox-active organic moiety. The modified nucleoside is capable of enzymatic incorporation into a nucleotide chain and allows for redox labelling of nucleotides.

An efficient overall two-step strategy for the synthesis of (E)-5-aminoallyl-pyrimidine-5′-triphoshate, starting from commercially available pyrimidine-5′-triphosphate is described. The method involves regioselective iodination of pyrimidine-5′-triphosphate, followed by the palladium-catalyzed Heck coupling with allylamine. The catalytic reaction is highly stereoselective and compatible with many functional
