Derivations from Asebotin to Sakuranetin and from Phlorizin to Naringenin

In order to clarify the difference between asebotin and phlorizin, the derivation of asebotin to sakuranetin and of phlorizin to naringenin was investigated. Triacetylasebogenin (III), derived from asebotin in two steps, was dehydrogenated with N-bromosuccinimide and 2, 6, 4'-triacetoxy 4-metho...

Zusammenfassung:In order to clarify the difference between asebotin and phlorizin, the derivation of asebotin to sakuranetin and of phlorizin to naringenin was investigated. Triacetylasebogenin (III), derived from asebotin in two steps, was dehydrogenated with N-bromosuccinimide and 2, 6, 4'-triacetoxy 4-methoxychalcone (IV) was obtained. IV was converted into sakuranetin by its treatment with diluted hydrochloric acid. Phlorizin was converted into naringenin by the same treatment as that of asebotin.
