title: Synthesis of L-arabinose-containing fragments of the oat root saponin Avenacin A-1.
abstract: Chemical syntheses of two disaccharides, benzyl beta-D-glucopyranosyl-(1-->2)-alpha-L-arabinopyranoside (1) and benzyl beta-D-glucopyranosyl-(1-->4)-alpha-L-arabinopyranoside (2), and a trisaccharide, benzyl beta-D-glucopyranosyl-(1-->2)-3-O-acetyl-4-O-(beta-D-glucopyranosyl)-alpha-L-arabinopyranoside (3), related to oat root triterpenoid saponin Avenacin A-1 are reported.
