Enantioselective Palladium-Catalyzed [3C + 2C] and [4C + 3C] Intramolecular Cycloadditions of Alkylidenecyclopropanes
(American Chemical Society, 2018-06-04)We report a highly enantioselective [3C + 2C] intramolecular cycloaddition of alkylidenecyclopropanes (ACPs) and alkenes. The best results are obtained by using sterically demanding chiral phosphoramidite ligands derived ... -
Gold(I)-catalyzed enantioselective cycloaddition reactions
(Beilstein-Institut, 2013)In recent years there have been extraordinary developments of gold(I)-catalyzed enantioselective processes. This includes progress in the area of cycloaddition reactions, which are of particular interest due to their ... -
Gold(I)‐Catalyzed Cascade Cycloadditions between Allenamides and Carbonyl‐Tethered Alkenes: An Enantioselective Approach to Oxa‐Bridged Medium‐Sized Carbocycles
(Wiley, 2013)Gold standard: Allenamides react with aldehydes or ketones having γ, δ, or ε alkenyl groups, upon activation with suitable gold catalysts, to provide oxa-bridged systems containing seven- to nine-membered carbocycles, in ... -
Highly Enantioselective Iridium(I)-Catalyzed Hydrocarbonation of Alkenes: A Versatile Approach to Heterocyclic Systems Bearing Quaternary Stereocenters
(Wiley, 2021)We report a versatile, highly enantioselective intramolecular hydrocarbonation reaction that provides a direct access to heteropolycyclic systems bearing chiral quaternary carbon stereocenters. The method, which relies on ... -
Transition Metal Promoted Transformations of Alkylidenecyclopropanes
(2020)Esta tesis doctoral explora la reactividad de los alquilidenciclopropanos (APCs) con distintos metales de transición. En el capítulo 1, se describe el desarrollo de variables enantioselectivas de las reacciones de cicloadición ...
