Catalyst-Controlled Chemodivergent Reactivity of Vinyl Cyclopropanes: A Selective Approach toward Indoles and Aniline Derivatives

Autor: Santosh Kumar Keshri, Suchithra Madhavan, Manmohan Kapur

Publikováno v: Organic Letters. 24:9043-9048

Herein, we disclose a catalyst-controlled chemodivergent approach to access C2-substituted indoles and diverse aniline derivatives with good chemo- and stereoselectivity by employing vinylcyclopropanes (VCPs) as coupling partners via a tandem C-H/C-C

Rh(III)-Catalyzed C(7)–H Alkylation of Quinolines in the Synthesis of Angular π-Extended Pyrroloquinolines for Single-Component White-Light Emission

Autor: Nandkishor Prakash Khot, Paritosh Mahato, Sajeev T. K., Saptarshi Mukherjee, Manmohan Kapur

Publikováno v: Organic Letters. 24:2186-2191

Reported herein is a sustainable approach for a regioselective, Rh(III)-catalyzed C(7)-H alkylation of 8-aminoquinolines via metal carbene migratory insertion. This transformation displays a high functional group tolerance and exquisite site selectiv

A switch to vinylogous reactivity of vinyl diazo esters for the C–H allylation of benzamides by merging cobalt and photoredox catalysis

Autor: Nandkishor Prakash Khot, Nitish Kumar Deo, Manmohan Kapur

Publikováno v: Chemical Communications. 58:13967-13970

Herein, a de novo vinylogous reactivity of vinyl diazo esters in the C–H bond allylation of benzamides has been developed by coalescing cobalt and photoredox catalysis via C–H activation/allyl carbene migratory insertion.

Ruthenium-catalyzed oxidative coupling of vinylene carbonate with isoxazoles: access to fused anthranils

Autor: Manmohan Kapur, Pravin Kumar

Publikováno v: Chemical Communications. 58:4476-4479

A ruthenium-catalyzed oxidative coupling of vinylene carbonate with isoxazoles has been developed to achieve the direct C-H formylmethylation of a diverse array of arylisoxazoles utilizing the isoxazole ring as the directing group. A simple manipulat

The winning team reached the terra incognita: Enantioselective synthesis of ferrocene 1,3-derivatives via distal C-H activation by Pd(II)/norbornene cooperative catalysis

Autor: Princi Gupta, Prakash Chandra Tiwari, Suchithra Madhavan, Manmohan Kapur

Together they solved the cold case! Activation of the distal C-H bonds of ferrocene and its stereoselective functionalization is not a dream anymore. Here we report, regio-and stereo selective catalytic distal C-H functionalization of ferrocenes actu
