Quinoxalines belong to a class of excellent heterocyclic scaffolds owing to their wide biological properties and diverse therapeutic applications in medicinal research. They are complementary in shapes and charges to numerous biomolecules they interact with, thereby resulting in increased binding affinity. The pharmacokinetic properties of drugs bearing quinoxaline cores have shown them to be relatively easy to administer either as intramuscular solutions, oral capsules or rectal suppositories. This work deals with recent advances in the synthesis and pharmacological diversities of quinoxaline motifs which might pave ways for novel drugs development.

Full control over multiple competing coupling sites would enable straightforward access to densely functionalized compound libraries. Historically, the site selection in Pd0-catalyzed functionalizations of poly(pseudo)halogenated arenes has been unpredictable, being dependent on the employed catalyst, the reaction conditions, and the substrate itself. Building on our previous report of C?Br-selective functionalization in the presence of C?OTf and C?Cl bonds, we herein complete the sequence and demonstrate the first general arylations and alkylations of C?OTf bonds (in <10 min), followed by functionalization of the C?Cl site (in <25 min), at room temperature using the same air- and moisture-stable PdI dimer. This allowed the realization of the first general and triply selective sequential C?C coupling (in 2D and 3D space) of C?Br followed by C?OTf and then C?Cl bonds. Do you like my blog?

Background: Michaelis-Arbuzov reaction is one of the well studied reaction in phosphorus chemistry and used for the synthesis of phosphonates, phosphinates and phosphine oxides. Phosphonates are not only versatile intermediates in synthetic organic chemistry but also plays a vital role in biological activity. The usage of niobium(V) chloride as a catalyst has attracted the considerable attention due to its low hygroscopic character, high stability, cost effective, low loading and ease of handling. Methods: The present study describes the synthesis of a series of various aryl/heterocyclic substituted phosphonates/phosphinates of 2-chloroquinoxaline 3(a-e) and 6-iododibenzo[d,f][1,3]dioxepine 5(a-e) using an expeditious catalyst, niobium(V) chloride by Michaelis-Arbuzov reaction and evaluated their antimicrobial and antioxidant activities. Results: A simple, efficient and new synthetic protocol was developed for the synthesis of quinoxalinyl and dibenzodioxepinyl phosphonate/phosphinate derivatives (3a-e/5a-e) in good yields using niobium(V) chloride as a catalyst. Biological data revealed that compound 5c exhibited potent antimicrobial activity and the compounds 3e and 5e good antioxidant activity. Conclusion: From the results it was concluded that niobium(V) chloride was an efficient catalyst for the synthesis of quinoxalinyl and dibenzodioxepinyl phosphonate/phosphinate derivatives and also exhibited good antimicrobial and antioxidant activities.

The N,N-disubstituted hydrazones of ethyl alpha-ethoxalyl carboxylic esters exist as tautomeric mixtures of the imine and enamine forms; the imine form is represented by two configurational isomers, and the enamine form has the Z configuration stabilized by an intramolecular hydrogen bond.The tautomeric equilibrium is shifted toward the enamine form with increase in the volume of the substituents at the second nitrogen atom.In the methylarylhydrazones of ethoxalylacetic ester the enamine form is favored by the introduction of electron-withdrawing substituents into the aromatic r ing at the second nitrogen atom.In the series of hydrazones of the same type there is an irregular variation of the tautomeric composition with succesive increase in the volume of the alpha substituent with the largest content of the enamine form in the derivatives of alpha-ethoxalylpropionic ester.
