  solvent, the reactions could be performed in yields ranging from 40 to 70%. Most of the products were tested for their antimicrobial, antifungal, antioxidant, and cytotoxic (MCF-7) activity. Xanthone, thioxanthone, fluorenone, benzophenone, 2-benzoylpyridine, dibenzofuran, and dibenzothiophene were deprotonated using a base prepared in situ from MCl2·TMEDA (M = Zn or Cd; TMEDA = N,N,N′,N′-tetramethylethylenediamine)

• Laccase-Catalysed Homocoupling of Primary Aromatic Amines towards the Biosynthesis of Dyes

  AbstractColoured disubstituted benzoquinonimine trimeric structures are obtained as main reaction products of the oxidation of p‐electron donor primary aromatic amines using two different laccases, CotA‐laccase from Baccilus subtilus and TvL from Trametes versicolor. These orange‐red to purple products, presenting high molar extinction coefficients, presumably result from oxidative homocoupling reactions, through the formation of NC bonds at positions 2 and 5, of the laccase oxidised intermediate as showed in the proposed oxidative pathway. The product of 1,4‐phenylenediamine is shown to be the trimer known as Bandrowski’s base which has an established role in hair and fur dyeing. Our results also show that the occurrence and/or rates of oxidation of aromatic amines are strongly dependent on the presence of p‐electron releasing substituents in the aromatic ring and are independent on the properties of the enzyme used. Overall our data contribute for (i) understanding key features of laccase reactivity with p‐substituted aromatic amines and (ii) establishing enzymatic processes that lead to the synthesis of coloured bio‐products under mild conditions with potential impact in the cosmetic and dye industries.magnified image
• Convenient and Reliable Routes Towards 2-Aminothiazoles: Palladium-Catalyzed<i>versus</i>Copper-Catalyzed Aminations of Halothiazoles

  AbstractTwo efficient methods for the amination of 2‐halothiazoles are presented here. A first protocol requires a Pd/L system. Several 2‐aminothiazoles were synthesized under optimized conditions and isolated in good yields. The first palladium‐catalyzed CN coupling reactions between 2‐halothiazoles and primary alkylamines are presented. In a second part, ligand‐free copper‐catalyzed aminations of 2‐halothiazoles by alkylamines and aniline in a green solvent have been developed. The protocol is very effective for primary and secondary amines and perfectly tolerates the presence of another halide moiety on the 2‐halothiazole. The reaction occurs under the assistance of microwave irradiation, which drastically decreases the reaction time. The reaction leads to the formation of 2‐aminothiazoles, key molecules in pharmaceutical research.magnified image
• Copper-catalyzed oxidative C‒H, N‒H coupling of azoles and thiophenes

  C-H, N-H coupling of azole and thiophene derivatives takes place in the presence of a catalytic amount of Cu(OAc)(2) and an additive. The reaction of azoles smoothly occurs with several amines and amides catalyzed by 20 mol % of Cu(OAc)(2)-2PPh(3) and 4 equiv of NaOAc under O-2 or in the presence of Ag2CO3 under N-2. The coupling reaction leads to a facile synthesis of a N-substituted analogue of 2,5-diarylthiazole, which shows photoluminescent properties with extended pi-conjugation. Spectroscopic characteristics of the obtained thiazole derivatives are discussed by measurements of UV-vis absorption and photoluminescent spectra. Under the reaction conditions using Ag2CO3 as an additive and Cu(OAc)2-2PPh3 as a catalyst, thiophene derivatives also react with 2-pyrrolidone to undergo C-H, N-H amidation. (C) 2012 Elsevier Ltd.
