The final structure of robinin and biorobin and their total synthesis


, p. 215 - 218 (2007/10/10)

Robinin has been proved by total synthesis and by methylation analysis using GC-MS to be kaempferol-3- O-(6-O-α-l-rhamnopyranosyl -β-d-galactopyranoside)-7-O-α-l-rhamnopyranoside and not, as claimed by Maksjutina et al., a mixture of 4 glycosides containing the 7-O-rhamnosyl moiety in the α- and β-furanoside as well as in the α- and β-pyranoside forms. The assumption that the 3-O-rhamnosido -galactose moiety contained furanoid rings was also disproved.
