Synthesis, spectral characterization, crystal structure, cytotoxicity and apoptosis—Inducing activity of two derivatives of 2-hydroxy-1,4-naphthaquinone

A phenaxazone compound [5H-Benzo[a]phenoxazin-5-one (BP)] along with an aminoquinone[2-[(o-hydroxyphenyl)amino]-1,4-naphthaquinone (HAN)] derivatives were synthesized from lawsone using ultrasound irradiation technique. The structure of the compounds were

Tautomerism in o-hydroxyanilino-1,4-naphthoquinone derivatives: Structure, NMR, HPLC and density functional theoretic investigations

Structure and spectral characteristics of 'Ortho' ((E)-4-hydroxy-2-(2′-(4′-R)-hydroxyphenyl)-imino)-naphthalen-1(2H)-one) and 'para' (2-(2′-(4′-R)-hydroxyphenyl)-amino)-1,4-naphthoquinone) tautomers of o-hydroxyanilino-1,4-naphthoquinone derivatives (R=H,

Reactivity and Structure of N-Phenyl-1-naphthylamines and Related Compounds. Part 3. Reaction with Oxygen-centred Radicals

Comparison is made between products obtained by oxidation of N-phenyl-1-naphthylamines and 1-naphthyl phenyl nitroxides with peroxyl radicals.It is concluded that oxidation of the amines does not proceed to a considerable extent via the nitroxides.Comparison is also made of products obtained from these amines and nitroxides by oxidation with Fremy's salt.

Quinone Chemistry. Reaction of 2,3-Dichloro-1,4-naphthoquinone with 2-Aminophenols in Pyridine

The reaction of 2,3-dichloro-1,4-naphthoquinone (1) and 2-aminophenols (2) in pyridine furnished substituted 6-chloro-5H-benzophenoxazin-5-one (10), 5H-benzophenoxazin-5-one (8), 5H-benzophenoxazin-5-one-6-pyridinium chloride (6), 2-(2-hydroxyanilino)-1,4-naphthoquinone-3-pyridinium chloride (5), and 12H-benzophenoxazine-6,11-dione (7).It was observed that the nature and yields of the reaction products were greatly influenced by the substituent present in 2.The reaction mechanism for the formation of all products is discussed, and spectroscopic data are also given.This reaction for the first time led to a development of a novel, convenient synthesis of a new class of heterocyclic quinones (7).
