  Synthesis of benzamide-C-ribonucleosides by Pd-catalyzed aminocarbonylations

  摘要：

  A novel modular, efficient and practical methodology for preparation of p- and m-substituted benzamide-C-ribonucleosides was developed. Reaction of TBS-protected 3- and 4-bromophenyl-C-ribonucleosides 1 and 4 with Various primary and secondary amines or NH4Cl Under atmospheric pressure Of carbon monoxide and in the Presence of Pd(OAc)(2) and Xantphos lead to the corresponding amides 2a-j and 5a-j in high yields. Subsequent deprotection of silylated nucleosides by Et3N center dot 3HF or TFA afforded a series of free C-ribonucleosides 3a-j or 6a-j in excellent yields (20 examples). (C) 2009 Elsevier Ltd.
