p-Nitrobenzenesulfonyl nitroimidazole (p-NBSNI) (5) has been shown to be an efficient and convenient condensingagent in the coupling of protected nucleotide fragments. Its utility has been demonstrated by a direct comparison with previously-described condensingagents in the synthesis of various di- and tetradeoxy-nucleotides.
