“…Catechol derivatives are a promising group of compounds worthwhile for further investigation, which may lead to the discovery of selective acting, biodegradable agrochemicals having high human, animal, and plant compatibility 1. On the other hand, quinones are of considerable interest because many drugs such as doxorubicin, daunorubicin, and mitomycin C in cancer chemotherapy contain quinones 2, whereas various quinones have been found useful in industry 3. Some of them also exhibit antitumor and antimalarial activities 4, and many of them are also involved in enzyme inhibition and DNA cross‐linking 5.…”

The reaction of o -benzoquinone derived by the oxidation of catechols (1a-c) with some nucleophiles containing thiol group (2a-f) has been studied in various conditions, such as pH, nucleophile concentration, and scan rate, using cyclic voltammetry. In various conditions, based on an EC electrochemical mechanism ("E" represents an electron transfer at the electrode surface and "C" represents a homogeneous chemical reaction), the observed homogeneous rate constants (k o bs ) were estimated by comparison of the experimental cyclic voltammetric responses with the digital simulated results for each of the nucleophile. The results show that the magnitude of k o bs is dependent on the nature of the substituted group on the catechol ring and nucleophilicity of nucleophile. C 2009 Wiley Periodicals, Inc.

“…Since the work of KALEEM et al [1], poly(aminoquinone) (PAQ) has been recognized as an efficient polymer material for coatings [2] and adhesives [3] because of its extraordinary metal-affinity [4], good thermal resistance [5], impact strength [6], and reversible redox property [7]. PAQ has also found interesting applications as a binder in the prevention of polymer scale deposition [8] and as a supporter in the assembly of advanced functional materials [9].…”

Microwave irradiation was employed to assist the synthesis of poly(amino-quinone) (PAQ) from p-benzoquinone and diamines in solid state. The effects of power, time, and pattern (continuously or intermittently) of microwave irradiation on yield and intrinsic viscosity of PAQs were studied. It is shown that the continuous microwave irradiation at a high power leads to rapid increase of yield and a sudden halt in polymerization afterwards, due to the subsequent loss of volatile reactants at a high reaction temperature. Alternatively, the high-power microwave irradiation is applicable to raising the yield if used intermittently. In contrast, the low-power microwave irradiation favours the way of continuous exposure to ensure sufficient heat for polymerization. In both cases of high and low power, the yield and intrinsic viscosity can be further promoted by prolonging the exposure time. It is found that under a preliminarily optimized condition of intermittent irradiation at 490 W with six sequences of 5 min irradiation followed by 5 min interval, the yield and intrinsic viscosity of PAQ from p-benzoquinone and p-phenylene diamine can reach as high as 83% and 41.9 mL/g, respectively.

“…Many drugs in cancer chemotherapy contain quinones [4] whereas various other uses of quinones in industry have been reported as well. Polymers formed from the reaction of quinones with amines adhere to metals with sufficient affinity to displace water from a wet, rusty steel surface, are not wettable by water and resist most organic solvents [5,6].…”

SummaryThe synthesis of derivatives of aminoquinones with N-protected amino acids is reported here. 2-Amino-1,4-benzoquinone and 2-amino-l,4-naphthoquinone, prepared by the azide method in yields of 60 and 95% respectively, were coupled with N-Boc-protected amino acids including glycine, serine, proline and tyrosine, to give the correspondening derivatives. N, NI-Diisopropylcarbodiimide/1-hydroxybenzotriazole or N, N 1-dicyclohexylcarbodiimide/HOBt used as coupling reagents provided the expected products in satisfactory yields and purities as supported by TLC, HPLC and spectral analysis.
