Converting gem‐Dimethyl Groups into Cyclopropanes via Pd‐Catalyzed Sequential C—H Activation and Radical Cyclization.
TL;DR: In this article, a novel route to the synthesis of cyclopropane derivatives is described, where 1,1-Dimethyls in 2-(1, 1-dimethylalkyl)dimethyloxazolines are first converted into 1,3-diiodide derivatives via Pd-catalyzed sequential C−H activation and then radically cyclized to provide 2-( 1-alkylcylclopropyl), and the use of EtOAc as a solvent is crucial for the diiodination of the functionalized substrates.
Journal ArticleDOI
Cu-Catalyzed Cyclization/Coupling of Alkenyl Aldimines with Arylzinc Reagents: Access to Indole-3-diarylmethanes.
Rishi R. Sapkota,Rajkumar Tak,Vivek Aryal,Doleshwar Niroula,Nicholas C Secosky,Roshan K. Dhungana,Ramesh Giri +6 more
TL;DR: Sapkota et al. as mentioned in this paper reported a Cu(II)-catalyzed cyclization/coupling of alkenyl aldimines with arylzinc reagents to create indole-3-diarylmethane derivatives.
Journal ArticleDOI
Transition Metal‐Catalyzed C—H Activation Reactions: Diastereoselectivity and Enantioselectivity
TL;DR: In this article, a critical review discusses historical and contemporary research in the field of transition metal-catalyzed carbon-hydrogen (C-H) bond activation through the lens of stereoselectivity.
Journal ArticleDOI
Palladium‐Catalyzed Methylation and Arylation of sp2 and sp3 C—H Bonds in Simple Carboxylic Acids.
Ramesh Giri,Nathan Maugel,Jiao Jie Li,Donghui Wang,Steven P. Breazzano,Lindsey B. Saunders,Jin-Quan Yu +6 more
TL;DR: The use of preformed sodium carboxylates as substrates led to the first observation of facile Pd-insertions into sp3 β-C−H bonds in simple aliphatic acids as discussed by the authors.
