Abstract Reported herein is the first example of 2‐allylazaarenes in asymmetric catalysis. Highly γ‐selective allylation was demonstrated for activated ketones, including isatins and trifluoromethyl ketones. In presence either an amino‐acid‐based tertiary amine or quaternary ammonium salt catalyst, two series hydroxy‐containing moieties were installed at remote δ‐position azaarenes good chemical yields, excellent enantioselectivities, E / Z ratios. The success current reactions should...
Radical addition to olefins is a common and useful chemical transformation.
An enantioconvergent substitution of 3-substituted 3-chlorooxindoles with N-aryl glycines under visible light irradiation is reported. A transition-metal-free cooperative catalysis platform a dicyanopyrazine-derived chromophore (DPZ) as photoredox catalyst and chiral Brønsted acid effective for these transformations, which involve single-electron transfer redox step an enantioselective radical coupling. variety valuable 3-aminomethylene-3-substituted oxindoles can be directly synthesized...
Phenols are pivotal precursors and core motifs for various fine chemicals, bioactive molecules, functional materials, among which the site-selective syntheses of ortho-substituted phenols very attractive challenging. Here, we present a palladium-catalyzed dehydrogenation–coupling–aromatization protocol to access from cyclohexanols with primary alcohols. Broad substrate scope was achieved in this modular water hydrogen gas as clean byproducts. The ortho-mono- ortho-disubstitutions were...

Quaternary α-hydroxyl acids and their derivatives have attracted considerable attention because of unique broad functionalities. Herein, we successfully established a selective modular protocol to access quaternary acetates via dehydrogenative cross-coupling 1,2-diols primary alcohols by using tris-N-heterocyclic carbene iridium (tris-NHC-Ir, 0.05 mol %) complexes as catalysts Ba(OH)2 the base, along with generation byproducts water hydrogen gas. A plausible mechanism involving...
