  Synthesis of 5'-O-Amino-2'-Deoxypyrimidine and Purine Nucleosides: Building-Blocks for Antisense Oligonucleotides

  摘要：

  An efficient synthesis of 5'-O-amino-2'-deoxy analogs of uridine 1, thymidine 2, cytidine 3, 5-methylcytidine 3a, adenosine 4, and guanosine 5 was accomplished. The key step of 5'-O-N-bond formation in 2'-deoxynucleosides 1-5 was achieved via a Mitsunobu reaction in excellent yields. The 5'-O-amino nucleosides 1-5 are useful building-blocks for the synthesis of nucleoside dimers linked by a methylene(methylimino) (MMI) bridge. MMI is a novel phosphate surrogate for antisense oligonucleosides.
