nzoyl-2,3-O-isopropylidene-D-apio-beta-D-furanosyl bromide (8), prepar
ed in two steps from 2,3-O-isopropylidene-D-apio-beta-D-furanose (6),
was reacted with tris(trimethylsilyl)silane/AIBN in the presence of an
excess of a variety of activated olefins such as dimethyl maleate, me
thyl acrylate, acrylonitrile, methyl vinyl ketone, crotonaldehyde, cyc
lopent-2-enone, and cyclohex-2-enone to afford the corresponding C-api
osides 10 having beta-configuration.
