RESUMO
The synteses of the enantiomer of isoagatholactona (24), a very interesting natural diterpen from marine invertebrate Spongia officinallis, was carried out using the methyl isocopalate (67) with belongs to the copalic acid (68) by funcionalization of carbon-16. In view, many different methods were used like selenium dioxide, paladium chloride and photooxigenation, but the best results were formed with the photooxigenation. We obtained ent-isoagatholactona (66) which presented all the spectroscopic data similar to the isoagatholactona, except the optical activity which is the opposite of the natural product originaly isolated by Minale et all.
