Cyclization and rearrangement of diterpenoids. III. Synthesis of isoagatholactone and methyl spongia-13(16),-14-dien-19-oate

The synthesis of isoagatholactone has been effected by the successive oxidation of (14R)-isoagath-12-en-15-ol with selenium dioxide and manganese dioxide. Methyl spongia-13(16),14-dien-19-oate has been obtained by the cyclization of methyl lambertianate with 100% sulfuric or fluorosulfonic acid.
