Partial synthesis of [1β,2α,17,17-D4] gibberellin A1
Fuchs,Porzel,Schneider
, p. 448 - 452 (1997)
An efficient route for an alternative synthesis of gibberellin A1 from gibberellin A3 is described. Based on iodolactonisation the method provides access to gibberellin A1 labeled by deuterium with both high incorporation
