Pentenyl arabinofuranosides

Recent interest in oligoarabinans, have been triggered by their presence in the lipoarabinoman-nan polysaccharide component of the cell wall complex of mycobacteria [85]. Several research groups have employed -pentenyl arabinofuranosides in their approaches to oligoarabinans. 

The potency of this strategy relies ultimately in the sturdiness, and yet the possibility for chemoselective cleavage, of pentenyl arabinofuranosides (e. g. 175) [90]. Its value has been demonstrated recently with the synthesis of the pentenyl glycoside of mannose-capped dode-...
