The occurrence of unsaturated systems in natural products combined with the mildness and the wide range of applicability of CeCl3 promoted methodologies suggest several potential future synthetic applications within the field of total synthesis of biologically active molecules. On this concept, the use of CeCl3·7H2O-NaI system as an efficient heterogeneous promoter has been highlighted in the iodofunctionalization of carbon-carbon triple bonds. The study has shown that this method would be particularly interesting for the stereoselective formation of trisubstituted (Z)- or (E)-iodoalkenes by simply changing the nature of the solvent. The methodology has been successfully applied to the synthesis of (R)-1-[4,4-bis-(3-methyl-2-thienyl)-3-butenyl]-3-piperidinecarboxylic acid 1, named (R)-Tiagabine, which is a potent and selective γ-aminobutyric acid (GABA) uptake inhibitor with proven anticonvulsant efficacy in humans.

Rh(iii)-catalyzed C-H olefinic alkynylation of enamides for the stereospecific construction of synthetically useful Z-type enynamides is reported. This protocol displays good functionality tolerance and operational simplicity thus providing an alternative synthetic opportunity for the ease of access to specific 1,3-enyne derivatives.

Both eight-membered enamide rings and fused [4.2.0]aminocyclobutane- containing δ-lactams can be accessed from N-vinyl-β-lactams. The eight-membered rings are made through a [3,3] sigmatropic rearrangement. At elevated temperature, the eight-membered lact
Palladium-catalyzed carbene insertion into vinyl halides and trapping with amines

Palladium is shown to catalyze the three-component coupling of vinyl halides, trimethytsilyldiazomethane, and amines to generate allylamines. The mechanism is believed to Involve formation of an R-Pd=CHSiMe3 intermediate that undergoes migratio
