  A stereo- and regio-controlled synthesis of bromothiophenyl C-nucleosides. Tandem bromination-ribosylation via halogen dance process

  摘要：

  Metallation-ribosylation of 2-bromothiophene 1 when conducted at room temperature afforded the original glycosylated dibromothiophene 3b following a regiocontrolled halogen transfer-based halogen-dance process. Then, stereocontrolled reduction-cyclization of hemiacetals 3a-c allowed straightforward access to the halogenated thiophenyl-C-nucleosides 6a-c. (C) 2008 Elsevier Ltd. All rights reserved.
