1,4,2-Dioxazol-5-ones as Isocyanate Equivalents: An Efficient Synthesis of 2-Quinolinones via β-Keto Amides

Under thermal conditions, 1,4,2-dioxazol-5-ones are known to undergo decarboxylation followed by Lossen's rearrangement to yield isocyanates. Described herein is the in situ trapping of the resulting isocyanates with carbon nucleophiles to synthesize β-keto amides. Furthermore, a general and mild method for the conversion of the resulting β-keto amides into quinolin-2-ones is reported.

Metal-Free C-H [5 + 1] Carbonylation of 2-Alkenyl/Pyrrolylanilines Using Dioxazolones as Carbonylating Reagents

A novel metal-free C-H [5 + 1] carbonylative annulation of 2-alkenyl/pyrrolylanilines with dioxazolones has been established for the assembly of the privileged quinolinones and pyrrolyl-fused quinoxalinones. Entirely differing from the existing reports, the dioxazolones herein behave with an innovative chemistry and first emerge as carbonylating reagents to participate in annulation reactions. Moreover, this process features exceedingly simple operation (only solvent) and tolerates both vinyl and aryl substrates. Comprehensive mechanistic studies indicate that the formed isocyanate intermediate plays a crucial role in enabling the carbonylation annulation.

Synthesis of 2-Quinolinones via a Hypervalent Iodine(III)-Mediated Intramolecular Decarboxylative Heck-Type Reaction at Room Temperature

A hypervalent iodine(III)-mediated intramolecular decarboxylative Heck-type reaction of 2-vinyl-phenyl oxamic acids has been developed. The unique ring-strain-enabled radical decarboxylation mechanism is preliminarily revealed. This protocol features metal-free reaction conditions and operational simplicity, allowing the lactamization of 2-vinylanilines using a readily accessible carbonyl source and the synthesis of various 2-quinolinones with excellent chemoselectivity at room temperature.

Palladium-catalyzed arylation/cyclization/desulfonation cascades toward 4-aryl quinolin-2(1H)-ones with diaryliodonium salts

Palladium-catalyzed cascades of arylation/cyclization/desulfonation of ortho-aminocinnamate esters by using diaryliodonium salts afforded a wide range of 4-aryl quinolin-2(1H)-ones. As such, the desired 4-aryl quinolin-2(1H)-ones with potential biological activity has been synthesized in the yields of 34–96%.

Method for preparing 4-aryl-2-quinolinone through carbon dioxide

The invention discloses a method for preparing 4-aryl-2-quinolinone through carbon dioxide, and belongs to the technical field of carbon dioxide comprehensive utilization. The method comprises the following concrete process steps: in a dehydrated and deox

A Facile Synthesis of 5-Phenyl-Dibenzo[b, g][1,8]Napthyridines

The Vilsmeier Haack heterocyclization of 2-aryl amino-4-phenyl quinolines quinoline yielded the hitherto unknown 5-phenyl-dibenzo[b,g][1,8]naphthyridines in quantitative yield. The synthesis of aryl amines was achieved by the action of anilines on 2-chloro-4-phenyl quinoline, which in turn was sourced through the combes reaction of benzoyl acetanilides.

Palladium-Catalyzed Multi-Component Reactions of N-Tosylhydrazones, 2-Iodoanilines and CO2towards 4-Aryl-2-Quinolinones

A palladium-catalyzed three-component reaction between N-tosylhydrazones, 2-iodoanilines and atmospheric pressure CO2was developed whereby a tandem carbene migration insertion/lactamization strategy afforded 4-aryl-2-quinolinones in moderate to good yields. Notably, a wide range of functional groups were tolerated in this procedure. This protocol features the simultaneous formation of four novel bonds; two C?C, one C=C and one C?N (amide), representing an efficient methodology for incorporation of CO2into heterocycles.

Lactamization of sp2C?H Bonds with CO2: Transition-Metal-Free and Redox-Neutral

The first direct use of carbon dioxide in the lactamization of alkenyl and heteroaryl C?H bonds to synthesize important 2-quinolinones and polyheterocycles in moderate to excellent yields is reported. Carbon dioxide, a nontoxic, inexpensive, and readily available greenhouse gas, acts as an ideal carbonyl source. Importantly, this transition-metal-free and redox-neutral process is eco-friendly and desirable for the pharmaceutical industry. Moreover, these reactions feature a broad substrate scope, good functional group tolerance, facile scalability, and easy product derivatization.

Practical route to 2-quinolinones via a Pd-catalyzed C-H bond activation/C-C bond formation/cyclization cascade reaction

Quinolinone derivatives were constructed via a Pd-catalyzed C-H bond activation/C-C bond formation/cyclization cascade process with simple anilines as the substrates. This finding provides a practical procedure for the synthesis of quinolinone-containing alkaloids and drug molecules. The utility of this method was demonstrated by a formal synthesis of Tipifarnib.

A straight forward synthesis of 4-aryl substituted 2-quinolones via Heck reaction

A variety of aryl halides have been successfully coupled with different olefins via Heck reaction in the presence of an active stimulant (Pd-NHC). An efficient one pot protocol for the easy access of structurally diverse 4-aryl-2-quinolones via domino Heck/cyclization reaction has been developed. This journal is
