  A mild Knoevenagel coupling reaction between an indol-2-thione and a ribofuranose derivative was developed for the synthesis of 2-benzylthio-5,6-dichloro-3-(β-D-ribofuranosyl)indole (12). 3-(β-D-ribofuranosyl)-2,5,6-trichloroindole (16) was prepared from 12 in 4 steps. A Lewis acid-mediated glycosylation method was then developed to prepare the targeted 2-haloindole C-nucleoside 16 stereoselectively

  Glycosylation involving D-ribose derivatives and various N-protected tert-butyl L-serinates can be achieved efficiently by careful choice of the activation method at the anomeric position and of the Lewis acid promoter. The conditions described allow the major formation of the P-anomer required for further elaboration to liposidomycin and caprazamycin analogues. (c) 2005 Elsevier Ltd. All rights reserved.
