  Nonoxidative chlorination of dialkyl phosphonates to dialkyl phosphorochloridites. A new approach to oligonucleotide synthesis

  摘要：

  Several dialkyl phosphonates and alkyl nucleoside 3'-phosphonates were transformed into the corresponding highly reactive phosphorochloridites without oxidation of phosphorus by use of tris(2,4,6-tribromophenoxy)-dichlorophosphorane (BDCP) as a chlorinating reagent. The reaction was applied to internucleotidic bond formation. 2-Cyanoethyl and methyl nucleoside 3'-phosphonates were prepared in high yields and were stable enough to be used as starting materials in oligonucleotide synthesis. Examination of dodecathymidylate synthesis on a polymer support, using 2-cyanoethyl or methyl nucleoside 3'-phosphonate as building blocks, showed that the 2-cyanoethyl nucleoside 3'-phosphonate was more effective.
