Five mononitro-, three dinitro- and one trinitrobenzanthrones have been synthesized by the modified Ullmann cross-coupling reaction between nitro-substituted 1-iodonaphthalene and methyl 2-iodo-benzoates, followed by the Friedel-Crafts ring closure of the resulting 2-(1-naphthyl)benzoic acid derivatives.
Palladium-Catalyzed Direct <i>N</i>-Arylation of Nucleosides, Nucleotides, and Oligonucleotides for Efficient Preparation of dG−<i>N</i><sup>2</sup> Adducts with Carcinogenic Amino-/Nitroarenes
A method for direct palladium-catalyzed N-arylation reaction of nucleobases was developed for the convenient synthesis of DNA adducts with carcinogenic compounds. Using xantphos as the phosphine ligand and tetraethylammonium fluoride as the base in DMSO, several o-iodonitroarenes could be efficiently coupled with 2‘-deoxyguanosine, 2‘-deoxyadenosine, and 2‘-deoxycytidine. The presence of a 3‘-phosphate
