  3. 21 de abr. de 2020 · The last approach hinges on the direct modification of indoles by radical addition to the pyrrole subunit of the indole nucleus. Application of this methodology to the total synthesis of melatonin and the alkaloids mersicarpine, caulerpine, and the pentacyclic skeleton of tronocarpine is briefly discussed.

  4. The xanthate methodology is applicable for additions to strained alkenes such as cyclobutenes, azetines, and cyclopropenes <2000TL9815>. The intermolecular addition of the radical obtained from the xanthate to suitable allylic or homoallylic amines proved to be the key step for the construction of various nitrogen heterocycles <1999TL3701>.
