Crystal structures and packing motifs of 2,3-diphenylquinoxaline and 2,3-diphenylbenzo[g]quinoxaline

White plates of 2,3-diphenylquinoxaline crystallize in the monoclinic space group P21/n with Z=4 and a=6.0325(3) A, b=10.9516(6) A, c=22.5985(13) A, and β=95.107(2)°. The phenyl rings in 2,3-diphenylquinoxaline form torsion angles of 36.88(5)°

Near-infrared-emitting heteroleptic cationic iridium complexes derived from 2,3-diphenylbenzo[g] quinoxaline as in vitro theranostic photodynamic therapy agents

Five heteroleptic cationic iridium complexes with a π-expansive cyclometalating 2,3-diphenylbenzo[g]quinoxaline (dpbq) ligand (C^N ligand) and different diimine ligands (N^N ligands) (i.e. 2,2′-bipyridine (bpy, 1), phenanthroline (phen, 2), 2-(2-pyridinyl

Dual visible/NIR emission from organometallic iridium(III)complexes

A series of four substituted benzo[g]quinoxaline species have been synthesised and utilised as cyclometalating ligands for iridium(III). The ligands (L1-L4)were synthesised and isolated in good yield following the condensation of 2,3-diaminonaphthalene wi

BSA-encapsulated cyclometalated iridium complexes as nano-photosensitizers for photodynamic therapy of tumor cells

Photodynamic therapy is a promising treatment method. The development of suitable photosensitizers can improve therapeutic efficacy. Herein, we report three iridium complexes (Ir1, Ir2, and Ir3), and encapsulate them within bovine serum albumin (BSA) to f

HBTU-catalyzed simple and mild protocol for the synthesis of quinoxaline derivatives

HBTU-catalyzed, simple, mild, and effective protocol for the synthesis of quinoxalines has been established. The reaction between 1,2-diamines, benzil, and catalytic amount of HBTU in ethanol resulted into quinoxalines. Various aliphatic, aromatic and het

Dowex 50W: Mild efficient reusable heterogeneous catalyst for synthesis of quinoxaline derivatives in aqueous medium

An efficient, simple and eco-friendly procedure is reported in presence of heterogeneous Dowex 50W catalyst in aqueous medium under refluxing condition to produce quinoxaline derivatives. Catalyst has participated in condensation reaction between 1,2-diamines and various aromatic 1,2-diketones smoothly with excellent yield of the products in short reaction times. Dowex 50W was used more than five times in this reaction separately and showed an excellent recyclability throughout the reaction.(figure presented).

Sequentially Pd/Cu-Catalyzed Alkynylation-Oxidation Synthesis of 1,2-Diketones and Consecutive One-Pot Generation of Quinoxalines

We report a simple and efficient one-pot synthesis of 1,2-diketones by concatenation of two Pd/Cu-catalyzed processes: Pd0/CuI-catalyzed Sonogashira coupling of terminal alkynes with aryl (pseudo)halides furnishes internal alkynes, which are directly transformed by PdII/CuII-catalyzed Wacker-type oxidation with DMSO and oxygen as dual oxidants to furnish 1,2-diketones. With this efficient, catalyst economical process, various aryl iodides and triflates are efficiently transformed in high yields into symmetrically and unsymmetrically substituted 1,2-diketones with various functional groups. This process can be readily extended to a consecutive one-pot synthesis of quinoxalines in a diversity-oriented fashion.

Synthesis of Naphthalene based Quinoxaline derivatives using surfactant and their biological applications as drugs

One pot synthesis of Naphtaleno-4, 6-(2, 4-quinoxaline) derivatives were achieved using direct coupling reaction by retaining 2,3-diaminonaphthalene as common with different forms of diketones viz., Benzil, 4, 4'-dimethyl benzil and 4, 4'-difluoro benzil.

Synthesis of benzo[g]quinoxaline-5,10-dione based pyridine derivatives and their antimycobacterial activity

The newly synthesized compounds were screened for their antimycobacterial activity by L.J. Slope (Conventional) Method. Compound 6h with 4-N(CH3)2 group at phenyl ring of above mentioned position has been reported as most active antimycobacterial compound and compound 6k with 4-CH3 substitution at phenyl above mentioned position has been reported as the least active antimycobacterial compound.

The newly synthesized compounds were submitted for their in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv by L.J. Slope (Conventional) Method. Compound 6e having 4-OCH3 at phenyl ring attached to 3-position of prop-2-enoyl group has been observed as the most active antimycobacterial compound, while compound 6h having 4-CF3 group on the above-mentioned position has been observed as the least active antimycobacterial compound of the newly synthesized series.
