Abstract New imidazo [4, 5-a] acridone derivatives were synthesized from the rearrangement
of 3 H-imidazo [4′, 5′: 3, 4] benzo [c] isoxazoles. New imidazo [4, 5-a] acridines were …

Carbanions of phenylacetonitriles, benzyl sulfones, and dialkyl benzylphosphonates add
nitroarenes at the ortho-position to the nitro group to form σ^ H σ H-adducts that, upon …

The syntheses and fluorescence properties of novel derivatives of pyrido [2′, 1′: 2, 3]
imidazo [4, 5-b] quinoline are described. The key intermediates (4-substituted)(3 …

A novel solvent-free, TfOH-promoted decyanative cyclization approach for the synthesis of 2,
1-benzisoxazoles has been developed. The reactions are complete instantly at room …

Abstract New derivatives of 2-(5-hydroxyimino-1-alkyl-4, 5-dihydro-1H-4-indazolyliden)-2-
arylacetonitriles were synthesized by the reaction of 1-alkyl-5-nitro-1H-indazole with …

Nucleophilic substitution of hydrogen in nitro derivative of imidazo [1, 2‐a] pyridine has been
used as a key step in the one‐pot synthesis of a new highly fluorescent heterocyclic system …

Nucleophilic substitution of hydrogen in 5-nitrobenzimidazole derivatives occurs upon
reaction with 4-methylbenzyl cyanide under basic conditions and proceeds with concomitant …

The discovery of a new variation on the Davis–Beirut reaction is described in which an
atypical heterocyclic framework (the anthranil or benzo [c] isoxazole framework) is formed as …

Nucleophilic substitution of hydrogen followed by intramolecular electrophilic aromatic
substitution in nitro drevitavies of indazole has been used as a key step in the one pot …
