Diastereoselective gold-catalyzed cycloisomerizations of Ene-ynamides
Couty, Sylvain,Meyer, Christophe,Cossy, Janine
, p. 6726 - 6730 (2006)
(Chemical Equation Presented) Around they go: 1,6-Ene-ynamides undergo highly diastereoselective gold-catalyzed cycloisomerizations that lead to functionalized cyclobutanones or carbonyl compounds with a 2-azabicyclo-[3.1.0] hexane subunit, depending on t
Synthesis of different ring-size heterocycles from the same propargyl alcohol derivative by ligand effect on Pd(0)
Kozawa, Yuji,Mori, Miwako
, p. 1499 - 1502 (2002)
The type of ligand on an allenylpalladium complex, which was prepared from propargyl alcohol derivative and Pd(0), plays an important role in determination of the ring size of the cyclized compound. An intermediary palladium complex bearing a monodentate ligand gave a cyclized compound via palladacycle, while that bearing a bidentate ligand gave one-carbon elongated cyclized compound via a η3-propargylpalladium complex.
Radical cascade cyclizations and platinum(II)-catalyzed cycloisomerizations of ynamides
Marion, Frédéric,Coulomb, Julien,Servais, Aurore,Courillon, Christine,Fensterbank, Louis,Malacria, Max
, p. 3856 - 3871 (2007/10/03)
Ynamides are tested as new partners in radical and organometallic transformations. A radical cascade involving a 5-exo-dig cyclization followed by a 6-endo-trig radical trapping transforms ynamides into hetero-polycyclic compounds such as isoindoles, isoindolinones and pyrido-isoindolones. Various ene-tosylynamides react with platinum(II) chloride and lead to bicyclic nitrogenated heterocycles. This unprecedented and easily operated process can be coupled with a hydrolysis of the intermediate cyclic tosylenamides in a one-pot transformation, which provides cyclobutanones.
Synthesis of cyclic dienamide using ruthenium-catalyzed ring-closing metathesis of ene-ynamide

Ring-closing metathesis of ene-ynamide, which has alkene and ynamide moieties in a molecule, using a second-generation ruthenium carbene complex produced nitrogen-containing heterocycles, which have a dienamide moiety, in high yields. Diels-Alder reaction
