2′,3′,5′-tri-O-acetyl-nucleosides in water has been developed. Furthermore, a long-chain selective glycerol-3-phosphocholine diacylation is elucidated. These reactions are environmentally benign, rapid, high yielding, and the products are readily purified. Importantly, this reaction may indicate a prebiotically plausible reaction pathway for the selective acylation of key metabolites to facilitate their

derivatives by organometallic ruthenium(II) arene anticancer complexes of the type [(eta(6)-arene)Ru(II)(en)X] where en = ethylenediamine, arene = biphenyl (Bip), tetrahydroanthracene (THA), dihydroanthracene (DHA), p-cymene (Cym) or benzene (Ben), X = Cl(-) or H(2)O using (1)H, (31)P and (15)N ((15)N-en) NMR spectroscopy. For mononucleosides, [(eta(6)-Bip)Ru(en)](2+) binds only to N7 of guanosine, to N7

based ruthenium(II) (1a) and osmium(II) (1d) complexes displayed modest anticancer activities against HeLa and HEK293 cell lines, the analogous rhodium(III) and iridium(III) complexes exhibited good potential (CC50 = 9–54 μM versus auranofin (3–9 μM)) against these cancer cell lines. Insightful NMR studies on the interaction between the DNA model guanosine 5′-GMP and the complexes 1b,c reveal a possible

uridine and the nucleotides 5′UMP, 5′CMP, 5′GMP and 5′IMP, and their characterization, carried out by elemental analysis, by studying the infraredspectra, diffuse reflectance and conductivity measurement. In the complexes of NiURA (and NiURD) with acetate, direct coordination of the metal ion to the C 4 O group of the pyrimidine ring is inferred from the changes observed on the infrared spectrum of
