Uses

Used in Pharmaceutical Industry:
Chalcone is used as a key intermediate in the synthesis of pharmacologically-interesting heterocyclic systems, such as pyrazolines and pyrimidines. These heterocyclic systems have potential applications in the development of new drugs with various therapeutic effects.
Used in Cancer Treatment:
Chalcone has demonstrated its potential as an antitumor agent, particularly in inhibiting the proliferation of human breast cancer cell lines, MCF-7 and MDA-MB-231. It achieves this by inducing apoptosis and blocking cell cycle progression in the G2/M phase, which can contribute to the development of novel cancer treatments.

Preparation

Chalcone is an aromatic ketone that forms the central core for a variety of important biological compounds, which are known collectively as chalcones.Chalcones can be prepared by an aldol condensation between a benzaldehyde and an acetophenone in the presence of sodium hydroxide as a catalyst.This reaction has been found to work without any solvent at all - a solid-state reaction. The reaction between substituted benzaldehydes and acetophenones has been used to demonstrate green chemistry in undergraduate chemistry education.In a study investigating green chemistry synthesis, chalcones were also synthesized from the same starting materials in high temperature water (200 to 350 °C).

Biological Activity

1,3-Diphenyl-2-propenone (chalcone) inhibits the proliferation of human breast cancer cell lines, MCF-7 and MDA-MB-231 by inducing apoptosis and blocking cell cycle progression in the G2/M phase. It is an inhibitor of Plasmodium falciparum cyclin-dependent protein kinases.

Silver-Catalyzed Intramolecular C-2 Selective Acylation of Indoles with Aldehydes: An Atom-Economical Entry to Indole-Indolone Scaffolds

A direct annulation reaction of N-(2-formylaryl)indoles has been developed, which can provide a new entry to biologically and medicinally important indole-indolone scaffolds via a silver-catalyzed direct oxidative coupling between aldehyde C H and sp2C H bonds for the first time. Remarkably, this strategy displayed excellent functional group compatibilities, thereby suggesting its wide potential for applications in developing and synthesizing new drug-like compounds containing indole-indolone frameworks.

Copper(II)-Promoted Oxidation/[3+2]Cycloaddition/Aromatization Cascade: Efficient Synthesis of Tetrasubstituted NH -Pyrrole from Chalcones and Iminodiacetates

A simple and highly efficient method for the preparation of tetrasubstituted NH -pyrrole from a wide range of chalcones and diethyl iminodiacetates via a Cu(OAc) 2 -promoted oxidation/[3+2]cycloaddition/aromatization cascade reaction has been developed. This reaction proceeds through dehydrogenations, deamination, and oxidative cyclization, affording the corresponding products in good to excellent yields. This convenient methodology for constructing tetrasubstituted NH -pyrroles has several advantages over existing methods, such as the use of easily accessible chalcones and readily available diethyl iminodiacetates, and mild reaction conditions. A wide range of substrates are tolerated.

Ranks of Carbon Leaving Groups in Alkene-forming Elimination

Carbon leaving groups in alkene-forming eliminations are exceptionally poor and their ranks show no correlation with the pKa of the conjugate carbon acid; the extent of bond cleavage in the transition state is evidently critical in determining rank.

Selective C-C bonds formation, N-alkylation and benzo[d]imidazoles synthesis by a recyclable zinc composite

Earth abundant metals are much less expensive, promising, valuable metals and could be served as catalysts for the borrowing hydrogen reaction, dehydrogenation and heterocycles synthesis, instead of noble metals. The uniformly dispersed zinc composites were designed, synthesized and carefully characterized by means of XPS, EDS, TEM and XRD. The resulting zinc composite showed good catalytic activity for the N-alkylation of amines with amines, ketones with alcohols in water under base-free conditions, while unsaturated carbonyl compounds could also be synthesized by tuning the reaction conditions. Importantly, it was the first time to realize the synthesis of 2-aryl-1H-benzo[d]imidazole derivatives by using this zinc composite under green conditions. Meanwhile, this zinc catalyst could be easily recovered and reused for at least five times.

One-pot two-step reaction of selenosulfonate with isocyanides and allyl alcohol under aqueous conditions: Atom-economic synthesis of selenocarbamates and allyl sulfones

In many reactions involving selenosulfonate or thiosulfonate, the sulfone group often leaves in form of benzenesulfinic acid or sodium benzenesulfinate. A one-pot two-step reaction of selenosulfonate with isocyanides and allyl alcohol under aqueous conditions to afford selenocarbamates and allyl sulfone compounds is reported. The sulfinic acid as the first-step side product is converted to the allyl sulfone compound by water promoted reaction with allyl alcohol. Water acts as both an oxygen source of selenocarbamates and as a promoter to drive the second step reaction. The reactions have the advantages of mild conditions, green, environment-friendly, and high atomic economy.

Chemoselective reduction of ?,￠-unsaturated carbonyl and carboxylic compounds by hydrogen iodide

The selective reduction of ?,￠-unsaturated carbonyl compounds was achieved to produce saturated carbonyl compounds with aqueous HI solution. The introduction of an aryl group at an ? or ￠ position efficiently facilitated the reduction with good yield. The reaction was applicable to compounds bearing carboxylic acids and halogen atoms. Through the investigation of the reaction mechanism, it was found that Michael-type addition of iodide occurred to produce ￠-iodo compounds followed by the reduction of C-I bond via anionic and radical paths.

Boosting the catalytic performance of zinc linked amino acid complex as an eco-friendly for synthesis of novel pyrimidines in aqueous medium

Zinc linked amino acid complex, Zn(l-proline)2, is considered as a green catalyst for the synthesis of novel series of pyrimidine derivatives 5a–q. The pyrimidines 5a–q were prepared via two pathways: the first is a one-pot reaction of guanidines 3a–c with aromatic aldehyde 1 and acetophenones 2; and the second one is the reaction of guanidines 3a–c with different chalcones 4a–j in aqueous medium. The simplicity of the operation, the short reaction time, and the high efficiency (97%) are the main advantages of this protocol. Furthermore, the green aspects of this synthetic protocol were further investigated by examining the reusability of Zn(l-proline)2 complex throughout five consecutive cycles without a significant loss of catalytic activity. This new procedure has presented remarkable advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and high purities without using any organic solvents.

Synthesis of lithium/cesium-Zagronas from zagrosian natural asphalt and study of their activity as novel, green, heterogeneous and homogeneous nanocatalysts in the Claisen–Schmidt and Knoevenagel condensations

A novel, heterogeneous and homogeneous basic nanocatalysts were synthesized by grafting of lithium and cesium on zagrosian natural asphalt sulfonate (Li/Cs-Zagronas). The activity of these catalysts was examined in the Claisen–Schmidt and Knoevenagel condensations under mild reaction conditions. Li/Cs-Zagronas were characterized by FT-IR spectroscopy, scanning electron microscopy, X-ray diffraction, energy-dispersive spectroscopy, inductively coupled plasma and thermogravimetric analysis techniques. These nanocatalysts were removed by simple filtration and reused several times without any deterioration of activity.
