  Components for a combinatorial library of rigid azabicyclic α-L-fucose mimics: First X-ray crystal structure of a stable monoalkylated triazene formed by hydrogenation of an azide

  摘要：

  Photobromination of the rigid aza-bicyclic fucose mimic 3 gave a reactive glycosyl type bromide 7 as a divergent intermediate for the synthesis of both 7-O and 7-N linked bicyclic L-fucose derivatives by direct displacement with alcohols or amines. Displacement of the bromide 7 with sodium azide gave an azide 6 which on hydrogenation gave a stable monoalkyl triazene 5 the structure of which was established by X-ray crystallographic analysis. Hydrolysis of 7 allowed access to a monocyclic L-fucose mimic with a nitrogen substituent at C-5. (C) 1999 Elsevier Science Ltd. All rights reserved.
