1β-Hydroxygibberellin A5. Preparation and Comparison with Gibberellin A3

The preparation of 1β-hydroxygibberellin A5 from gibberellin A3 is described.Unlike its naturally occurring allylic isomer gibberellin A3, 1β-hydroxygibberellin A5 is stable to aqueous alkali and acid-catalysed aromatisation of ring A does not occur.Reasons for these differences, and for the hitherto unreported 3-epimerisation of gibberellin A3 by base, are discussed in terms of O-alkyl fission of the lactone bridge.
