Partial Synthesis of [1β,2α,17,17-D4] Gibberellin A1
摘要:
An efficient route for an alternative synthesis of gibberellin A(1) from gibberellin A(3) is described. Based on iodolactonisation the method provides access to gibberellin A(1) labeled by deuterium with both high incorporation of the isotope and high stereoselectivity at the positions 1 beta and 2 alpha. The additional deuterium labeling at C-17 was introduced via the corresponding 16-norketone resulting in [1 beta,2 alpha,17,17-D-4] gibberellin A(1).
