Organocatalyzed Domino Synthesis of New Thiazole-Based Decahydroacridine-1,8-diones and Dihydropyrido[2,3-d : 6,5-d']- dipyrimidines in Water as Antimicrobial Agents

Tandem Protocol for the Synthesis of Pyrano[3,2-c]quinolone Derivatives Using Taurine as a Green Bio-Organic Catalyst in Aqueous Medium

A series of pyrano[3,2-c]quinolone derivatives has been synthesized in the presence of taurine (2-aminoethanesulfonic acid) as a green bio-organic catalyst and water as the solvent. The target compounds were synthesized through the three-component reaction between aldehydes, malononitrile/ethylcyanoacetate, and 4-hydroxy-1-methyl-2(1H)-quinolone. The advantages of this protocol are excellent yields of products, short reaction times, cost efficiency, atom economy, and a simple work-up procedure with no need for extra purification techniques. Moreover, the catalyst can be easily recovered and reused for up to three cycles without losing any significant activity.

Recent Advances in the Application of Barbituric Acid Derivatives in Multicomponent Reactions

Abstract:

Barbituric acid is a pyrimidine heterocyclic organic compound, which is pharmacologically active. It is important to build structures containing various medicinal activities. This compound attracts the scientific research community in organic synthesis. It can be used in the synthesis of polyheterocyclic, natural, medicinal compounds, and organic sensors. Herein, the utilization of barbituric or thiobarbituric acid in multicomponent reactions is reported from 2016-2021 in this manuscript.

Barbiturates: A Review of Synthesis and Antimicrobial Research Progress

BACKGROUND

Barbituric acid and its derivatives have turned heads for several years as an indispensable class of compounds in the pharmaceutical industry because of their vast assortment of biological activities such as anticonvulsants, hypnotics, anti-diabetic, antiviral, anti-AIDS, anti-cancer, anti-microbial and anti-oxidant etc. Plethoras of studies have shed light on the properties, synthesis, and reactivity of these compounds. The depiction of multiple biological activities by barbiturates compelled us and by virtue of which herein we have mediated over the progress of synthesis of numerous kinds of compounds derived from barbituric acid with well-known and typical examples from 2016 to the present.

OBJECTIVE

The review focuses on the advancements in methods of synthesis of barbituric acid derivatives and their applications as antimicrobial agents.

CONCLUSION

This review will help future researchers to analyze the previous studies and to explore new compounds for the development of efficient antimicrobial drugs.
