Aerobic Acylarylation of α,β-Unsaturated Amides with Aldehydes

Herein, we illustrate that molecular oxygen (O2) is capable of promoting oxidative radical acylarylation of olefins with aliphatic aldehydes to afford acylated oxindoles in good yield (up to 97%). The key aspect of the process is the utilization of aldehyde auto-oxidation in developing aerobic radical olefin acylarylation. Kinetic studies confirm a lag phase for the reaction. Synthetic utility of the method is apparent via the preparation of biologically potent spirocyclic oxindoles and tetrahydrofuranoindolines.

Photocatalytic C-C Bond Activation of Oxime Ester for Acyl Radical Generation and Application

A unified strategy to generate acyl radical from oxime ester via selective C-C bond activation is reported. Under visible-light irradiation, single-electron transfer from fac-Ir(ppy)3 to related oxime takes place followed by a fast β-fragment of C-C bond to yield aryl and aliphatic acyl radicals, subsequently captured by diverse Michael acceptors. More interestingly, the single-electron transfer enables coupling with energy transfer of the excited fac-Ir(ppy)3 via enone intermediate formed in situ for cyclobutane formation.

Visible-Light-Mediated Photocatalytic Difunctionalization of Olefins by Radical Acylarylation and Tandem Acylation/Semipinacol Rearrangement

A novel method for the mild photoredox-mediated tandem radical acylarylation and tandem acylation/semipinacol rearrangement has been developed. The synthesis of highly functionalized ketones bearing all-carbon α- or β-quaternary centers has been achieved

Photocatalyst-free hypervalent iodine reagent catalyzed decarboxylative acylarylation of acrylamides with α-oxocarboxylic acids driven by visible-light irradiation

A hypervalent iodine(iii) reagent catalyzed carbonylarylation of acrylamides with α-oxocarboxylic acids driven by visible-light without a photoredox catalyst has been developed. The reactions generate the corresponding products in good yields at room temperature. Experiments indicate that a blue LED (450-455 nm) is the most effective energy for the cleavage of the oxygen-iodine bond to initiate the reaction. Mechanistic studies further demonstrate that the reaction undergoes a cascade decarboxylative radical addition/cyclization process along with releasing CO2 and H2.

UV light-mediated difunctionalization of alkenes through aroyl radical addition/1,4-/1,2-Aryl shift cascade reactions

UV light-mediated difunctionalization of alkenes through an aroyl radical addition/1,4-/1,2-aryl shift has been described. The resulted aroyl radical from a photocleavage reaction added to acrylamide compounds followed by cyclization led to the formation of oxindoles, whereas the addition to cinnamic amides aroused a unique 1,4-aryl shift reaction. Furthermore, the difunctionalization of alkenes of prop-2-en-1-ols was also achieved through aroyl radical addition and a sequential 1,2-aryl shift cascade reaction.

Acyl Radicals from Aromatic Carboxylic Acids by Means of Visible-Light Photoredox Catalysis

Simple and abundant carboxylic acids have been used as acyl radical precursor by means of visible-light photoredox catalysis. By the transient generation of a reactive anhydride intermediate, this redox-neutral approach offers a mild and rapid entry to hi

Iron-catalyzed oxidative 1,2-carboacylation of activated alkenes with alcohols: A tandem route to 3-(2-oxoethyl)indolin-2-ones

Oxindoles are important heterocyclic compounds that are found in a wide range of pharmaceutical agents and natural products. A new oxidative tandem route to the assembly of 3-(2-oxoethyl)indolin-2-ones from N-arylacrylamides and alcohols has been established by using inexpensive and environmentally benign iron catalysts and peroxides. In the presence of Fe(OAc)2 and tert-butyl hydroperoxide, a variety of arylacrylamides underwent the oxidative 1,2-carboacylation reaction with alcohols to give the corresponding 3-(2-oxoethyl)indolin-2-ones in moderate to good yields.
