Methyl gibberellate has been efficiently transformed into the 14B-hydroxygibberellin A7 methyl ester. The key step in the conversion was the rearrangement of the 3B-acetoxy-15B, 16B-epoxy-beyergibberellin A7 methyl ester to the target gibberellin ester by means of a titanium-amide pair, which is compatible with the highly reactive ring A of the gibberellin system.
