Functionalization of cinnamaldehyde to arylidene barbituric acid, catalyzed by Samarium(III) Chloride

Benzaldehyde and cinnamaldehyde were successfully condensed with barbituric acid using samarium(III) chloride in water for 2 h at room temperature. The products were confirmed through FTIR, UV-Vis and GC-MS analysis.

Knoevenagel condensation in aqueous media promoted by 2,2′-bipyridinium dihydrogen phosphate as a green efficient catalyst

A 2,2′-Bipyridine-based ionic compound named 2,2′-bipyridinium dihydrogen phosphate was synthesized by addition of phosphoric acid to a solution of 2,2′-Bipyridine in dichloromethane. After the characterization using FT-IR, mass, 1H, 13C and 31P NMR techniques, it was used as a Bronsted dicationic acidic catalyst for the promotion of the synthesis of 2-arylidene malononitrile and 5-arylidene barbituric acid derivatives via Knoevenagel condensation reaction in water. Some of the advantages of this method are the utilization of an easy preparable, cost-effective and eco-friendly organic salt as a catalyst within high rates and yields of the reactions, simple and quick work-up and acceptable reusability of the catalyst.

Microwave-associate synthesis of Co3O4 nanoparticles as an effcient nanocatalyst for the synthesis of arylidene barbituric and Meldrum's acid derivatives in green media

In this study, Co3O4 nanocatalysts were constructed in environmentally appropriate conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the magnetic properties of the samples were investigated by VSM. The application of this nanostructure in a catalytic process was further examined, and the results suggested that it could be used as a novel candidate for the synthesis of arylidene barbituric and Meldrum,s acid through Knoevenagel condensation of aldehydes by barbituric and Meldrum,s acid in aqueous media. The high yield of these nanocatalysts would be justified by the nature of the nanostructure as well as the experimental procedure developed in this study, which affected the physicochemical features of the products.

Synthesis of barbiturate-based methionine aminopeptidase-1 inhibitors

The syntheses of a new class of barbiturate-based inhibitors for human and Escherichia Coli methionine aminopeptidase-1 (MetAP-1) are described. Some of the synthesized inhibitors show selective inhibition of the human enzyme with high potency.

Mono C-alkylation and mono C-benzylation of barbituric acids through zinc/acid reduction of acyl, benzylidene, and alkylidene barbiturate intermediates

Through systematic exploration of reaction conditions, very efficient preparative procedures for obtaining large quantities of substituted 5-alkyl and 5-benzylbarbituric acids were developed. The procedure involves a two step preparation in which the second step is zinc dust/acid reduction. For preparation of 5-alkylbarbiturates, the first step is the preparation of either 5-acyl or 5-alkylidenebarbiturate. If 5-benzylbarbiturate is the target product, then the first step includes the preparation of 5-benzylidene. Regardless of the nature of the first step, all reactions presented synthetic yields around 90% and isolation and purification involves only crystallization.

Reductive C-alkylation of barbituric acid derivatives with carbonyl compounds in the presence of platinum and palladium catalysts

Effective synthetic procedures for the preparation of mono- and di-C-alkylated barbituric acid derivatives through palladium and platinum catalytic hydrogenation of solutions of barbituric acids (unsubstituted, N-mono, and N,N′-disubstituted barbituric acids) and carbonyl compounds (aliphatic and aromatic aldehydes and ketones).

CHLOROSULFONATION OF 5,5-DIPHENYLHYDANTOIN AND 5-ARYLIDENEBARBITURIC ACIDS

5,5-Diphenylhydantoin (1) by heating with chlorosulfonic acid gave a bis-sulfonyl chloride (2) in which the orientation of sulfonation is apparently meta/para.The chloride (2) was converted into 8 sulfonamides (3-10).Barbituric acid has been condensed with aromatic aldehydes to yield 18 5-arylidene derivatives (11-28).The reaction of chlorosulfonic acid with 5-benzylidenebarbituric acid (11) is discussed together with the subsequent reaction of the sulfonyl chloride with amines.The chlorosulfonation of other arylidenebarbituric acids (12-14, 22, 23, 26 and 28) has also been examined. Key words: 5,5-Diphenylhydantoin; 5-arylidenebarbituric acids; chlorosulfonation; sulfonamides; Michael addition.

Photopolymerizable diepoxides containing a nitrogen heterocycle

Diepoxides which may be photopolymerized in the presence or absence of a photosensitizer contain a group having conjugated unsaturation attached to a nitrogen heterocycle, such as a hydantoin or barbituric acid residue, forming part of an advanced diepoxi
