  The effect of the base in the fragmentation of nucleotide C4′ radicals

  摘要：

  A series of 3'-O-diethylphosphoryl-4'-alpha-[(2-halophenylethylthio)carbonyl] substituted esters of thymidine, cytidine, adenosine and guanosine are prepared by total synthesis and used as C4'-radical precursors in a competition kinetic method using tributyltin hydride as the reductant. The pseudo-first order rate constants for the C4'-radicals so generated decrease in the order guansoine>cytidine>adenosine>thymidine with that for guanosine being too rapid for determination by the present competition kinetic method. A (119)Sn NMR method is presented for estimation of the purity of tin hydride solutions. (C) 2002 Elsevier Science Ltd. All rights reserved.
