Divergent Asymmetric Synthesis of Polycyclic Spiroindolines via Cascade Cycloadditions Open
Comprehensive Summary The asymmetric construction of polycyclic spiroindolines featuring one or more quaternary stereocenters remains a significant challenge in synthetic chemistry. We report a highly chemoselective and stereoselective cas…
Kinetic resolution of 1-(1-alkynyl)cyclopropyl ketones <i>via</i> gold-catalyzed divergent (4 + 4) cycloadditions: stereoselective access to furan fused eight-membered heterocycles Open
The stereoselective construction of furan/pyrrole-fused eight-membered heterocycles via chiral gold-catalyzed (4 + 4) cycloadditions was realized.
Asymmetric β-arylation of cyclopropanols enabled by photoredox and nickel dual catalysis Open
An asymmetric β-arylation of cyclopropanols with aryl bromides was enabled by enantioselective photoredox and nickel dual catalysis.
Transition Metal-Catalyzed Selective Carbon–Carbon Bond Cleavage of Vinylcyclopropanes in Cycloaddition Reactions Open
In this review, transition metal-catalyzed methodologies and applications that exploit C-C bond cleavage of vinylcyclopropanes (VCPs) are summarized with a focus on cycloaddition and related addition reactions. Transition metals, including…
Synthesis of Lactamsvia Ir-Catalyzed C–H AmidationInvolving Ir-Nitrene Intermediates Open
x-membered lactams\nwere synthesized via either\nan amidation of sp3 C–H bonds or an electrophilic\nsubstitution of arenes via Ir-nitrene intermediates. With the employment\nof a readily available iridium catalyst in dichloromethane or hex…
Pd-catalyzed asymmetric allylic alkylations via C–H activation of N-allyl imines with glycinates Open
Facile access to versatile α,β-diamine esters derives from an unprecedented C–H activation to generate aza-π-allyl palladium intermediates asymmetrically.
Rhodium(I)‐Catalyzed Benzannulation of Heteroaryl Propargylic Esters: Synthesis of Indoles and Related Heterocycles Open
A de novo synthesis of a benzene ring allows for the preparation of a diverse range of heterocycles including indoles, benzofurans, benzothiophenes, carbazoles, and dibenzofurans from simple heteroaryl propargylic esters using a unified ca…
