A variety of 2-aminobenzonitriles were prepared from 2-arylindoles in good to excellent yields through tert-butylnitrite (TBN)-mediated nitrosation and sequential iron(III)-catalyzed C-C Bond cleavage in a one-pot fashion. The 2-aminobenzonitriles can be used to rapidly synthesize benzoxazinones by intramolecular condensation. The present method features an inexpensive iron(III) catalyst, gram scalable preparations, and novel C-C bond cleavage of indoles.

1,2,4-Triazoles and quinoxalines were found to display various pharmacological activities. Hence a series of 1- aryl-4-methyl-1,2,4-triazolo[4, 3-a]quinoxalines were synthesized. Due to various advantages of organic reactions under solvent-free conditions these compounds were developed using iodobenzene diacetate under solvent-free conditions. The synthesized compounds were characterized by elemental microanalysis, infrared spectroscopy, 1H NMR, 13C NMR and HRMS. All the synthesized compounds were investigated for their antitubercular activity and 5g was found to the most active compound.

The vortex fluidic device (VFD) is effective in modulating the synthesis of pyrimidine and quinoxaline-based compounds at room temperature and in high yield. The formation of the C?N bond occurs in the absence of a transition-metal catalyst, which avoids the contamination of the products with trace amounts of a transition metal. The systematic investigation of the operating parameters for the microfluidic platform in the confined operation mode established an optimum tilt angle of 45 for a 10 mm diameter borosilicate glass tube rotating at 5000 rpm.

The synthesis and photophysical data of new carbostyrils (quinoline-2(1H)-ones) with the longest hitherto observed absorption- and emission wavelengths are described. Introduction of 6-amino, 7-MeO, and 4-(CF3) substituents enabled us to rise the absorption and fluorescence maxima up to 414 and 557 nm, respectively. Supported by semi-empirical and ab initio calculations, the 6,7-(1,4-diazine)-fused carbostyril 23b displayed absorption maxima at up to 440 nm, with quantum yields of up to 0.9 and large Stokes shifts (> 100 nm), comparable to the best coumarin chromophores known. The new fluorophore is neither pH-sensitive between pH 6 and 10 nor susceptible to O2 quenching. At pH 3, the emitted light appears greenish-white, which arises from three different stages of protonation.
