Journal ArticleDOI
Copper‐Catalyzed Trifluoromethylation of Internal Olefinic C—H Bonds: Efficient Routes to Trifluoromethylated Tetrasubstituted Olefins and N‐Heterocycles.
TL;DR: In this article, the internal olefinic C-H bond cleavage was not involved in the rate-determining step, and a mechanism that involves radicals was proposed based on a TEMPO-quenching experiment of the trifluoromethylation reaction.
Journal ArticleDOI
Broensted Acid‐Promoted Cascade Alkylation/Cyclization of Pyrroles with N,N‐Dimethylaminomethyleneglutaconic Acid Dinitrile: A Concise Route to Cyclopenta[b]pyrroles.
Journal ArticleDOI
Broensted Acid‐Mediated Annulation of α‐Oxo Ketene Dithioacetals with Pyrroles: Efficient Synthesis of Structurally Diverse Cyclopenta[b]pyrroles.
Journal ArticleDOI
Copper-Mediated Intramolecular Oxidative C—H/C—H Cross-Coupling of α-Oxo Ketene N,S-Acetals for Indole Synthesis.
TL;DR: In this article, the authors studied the precursors of the CDC reaction in intramolecular C-H/C-H cross-dehydrogenative coupling (CDC) of thioalkyl-substituted α-acetyl or α-aroyl ketene N,S-acetals.
