Ethylene-Promoted versus Ethylene-Free Enyne Metathesis
Anne G. D. Grotevendt, Justin A. M. Lummiss, Melanie L. Mastronardi, and Deryn E. FoggJournal of the American Chemical Society2011 133 (40), 15918-15921Ethylene-Promoted versus Ethylene-Free Enyne Metathesis
Anne G. D. Grotevendt, Justin A. M. Lummiss, Melanie L. Mastronardi, and Deryn E. FoggJournal of the American Chemical Society2011 133 (40), 15918-15921The role of ethylene in promoting metathesis of acetylenic enynes is probed within the context of ring-closing enyne metathesis, using first- and second-generation Grubbs catalysts. Under inert atmosphere, rapid catalyst deactivation is observed by ...

From Highly Enantioselective Catalytic Reaction of 1,3-Diynes with Aldehydes to Facile Asymmetric Synthesis of Polycyclic Compounds
Mark Turlington, Yuhao Du, Samuel G. Ostrum, Vishaka Santosh, Kathryne Wren, Tony Lin, Michal Sabat, and Lin PuJournal of the American Chemical Society2011 133 (30), 11780-11794From Highly Enantioselective Catalytic Reaction of 1,3-Diynes with Aldehydes to Facile Asymmetric Synthesis of Polycyclic Compounds
Mark Turlington, Yuhao Du, Samuel G. Ostrum, Vishaka Santosh, Kathryne Wren, Tony Lin, Michal Sabat, and Lin PuJournal of the American Chemical Society2011 133 (30), 11780-11794(S)-1,1′-Binaphth-2-ol (BINOL) in combination with ZnEt2, Ti(OiPr)4, and biscyclohexylamine was found to catalyze the highly enantioselective (83–95% ee) addition of various 1,3-diynes to aldehydes of diverse structures. This method provides a convenient ...

Platinum(II) Chloride-Catalyzed Stereoselective Domino Enyne Isomerization/Diels−Alder Reaction
Mathias Schelwies, Andreas Farwick, Frank Rominger, and Günter HelmchenThe Journal of Organic Chemistry2010 75 (22), 7917-7919Platinum(II) Chloride-Catalyzed Stereoselective Domino Enyne Isomerization/Diels−Alder Reaction
Mathias Schelwies, Andreas Farwick, Frank Rominger, and Günter HelmchenThe Journal of Organic Chemistry2010 75 (22), 7917-7919Chiral 1,6-enynes were prepared via Ir-catalyzed allylic substitutions. Their platinum(II) chloride-catalyzed domino enyne isomerization/Diels−Alder reaction provided stereoselective access to complex heterocycles. Very high diastereoselectivity was ...

Asymmetric Allylic Alkylation in Combination with Ring-Closing Metathesis for the Preparation of Chiral N-Heterocycles
Johannes F. Teichert, Suyan Zhang, Anthoni W. van Zijl, Jan Willem Slaa, Adriaan J. Minnaard, and Ben L. FeringaOrganic Letters2010 12 (20), 4658-4660Asymmetric Allylic Alkylation in Combination with Ring-Closing Metathesis for the Preparation of Chiral N-Heterocycles
Johannes F. Teichert, Suyan Zhang, Anthoni W. van Zijl, Jan Willem Slaa, Adriaan J. Minnaard, and Ben L. FeringaOrganic Letters2010 12 (20), 4658-4660Asymmetric copper-catalyzed allylic substitution with methylmagnesium bromide is employed in combination with ring-closing olefin metathesis or ene−yne metathesis to achieve the synthesis of chiral, unsaturated nitrogen heterocycles. The resulting six- ...

Diastereoselective Synthesis of P-Stereogenic Heterocycles via Enyne Ring-Closing Metathesis
James Stephen Harvey, Guy T. Giuffredi and Véronique GouverneurOrganic Letters2010 12 (6), 1236-1239Diastereoselective Synthesis of P-Stereogenic Heterocycles via Enyne Ring-Closing Metathesis
James Stephen Harvey, Guy T. Giuffredi and Véronique GouverneurOrganic Letters2010 12 (6), 1236-1239A range of P-containing ene-diynes suitable for desymmetrization was prepared via a two-step process starting from phosphorus oxychloride. In the presence of the Hoveyda−Grubbs II catalyst, these substrates underwent diastereoselective enyne ring-...
