Methanolysis or sodium borohydride reduction of the 3-acetoxy-7,19-dimethyl ester of gibberellin A13 20-toluene-p-sulphonyl anhydride afforded, respectively, the unusual 19-orthoester or epimeric 19-acetals as the major products rather than the products of simple displacement of the 20-toluene-p-sulphonoxy-group. The structure of the 19-orthoester was proven by X-ray analysis.
