Synthesis of 4-epi-Gibberellin A12 from ent-7a,18-dihydroxy-kaur-16-ene
For some time we have been working on the partial synthesis of diterpenes, using ent-kaurene type tetracyclic diterpenes from Canary species of Sideritis as starting material. One of our objects was the synthesis of compounds with a gibbane skeleton and in this context we carried out a cyclo B reduction via benzylic acid rearrangements 2. New we have synthesized 4-epi-giberellin A12 from epicandicandiol 3 (ent-7a,18-dihydroxy-kaur-16-ene) (I).
