Applications of Friedel-Crafts reactions in total synthesis of natural products

Over the years, Friedel-Crafts (FC) reactions have been acknowledged as the most useful and powerful synthetic tools for the construction of a special kind of carbon-carbon bond involving an aromatic moiety. Its stoichiometric and, more recently, its catalytic procedures have extensively been studied. This reaction in recent years has frequently been used as a key step (steps) in the total synthesis of natural products and targeted complex bioactive molecules. In this review, we try to underscore the applications of intermolecular and intramolecular FC reactions in the total syntheses of natural products and complex molecules, exhibiting diverse biological properties.

On-water chemistry: Copper-catalyzed straightforward synthesis of benzo[b]furan derivatives in neat water

A more sustainable protocol leading to 2-alkyl- or 2-aryl-substituted benzo[b]furans is reported, involving a copper-TMEDA complex which catalyzes the transformation of readily available ketone derivatives into the corresponding benzofurans in good to excellent yields. The reaction is accomplished using water as the solvent without organic cosolvents, and one example of catalyst reutilization is also presented.

Bio-based nickel alginate and copper alginate films with excellent flame retardancy: Preparation, flammability and thermal degradation behavior

A bio-based nickel alginate film and copper alginate film were prepared via a facile ion exchange and casting approach. Their flame retardancy, thermal degradation and pyrolysis behavior, and thermal degradation mechanism were investigated systematically by the limiting oxygen index (LOI), vertical burning (UL-94), microscale combustion calorimetry (MCC), thermogravimetric analysis (TGA), thermogravimetric analyzer coupled with Fourier transform infrared analysis (TG-FTIR) and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS). It was shown that the nickel alginate film had a much higher LOI value (50.0%) than those of the sodium alginate film (24.5%) and copper alginate film (23.0%). Moreover, the nickel alginate film passed the UL-94 V-0 rating, while the sodium alginate film and copper alginate film showed no classification. Importantly, the peak of heat release rate (PHRR) of the nickel alginate film in the MCC test was much lower than those of the copper alginate film and sodium alginate film. This indicated that the introduction of nickel ions decreased the release of combustible gases. TGA results showed that the addition of copper ions and nickel ions accelerated the thermal degradation of alginates and changed the thermal degradation mechanism of the alginates. TG-FTIR and Py-GC-MS results indicated that the pyrolysis of copper alginate and nickel alginate produced much less flammable products than that of sodium alginate in the whole thermal degradation process. Finally, a possible degradation mechanism for copper alginate and nickel alginate was proposed. The results of our study provide useful information for understanding the flame retardancy mechanism of alginate as well as for designing bio-based materials with excellent fire retardancy.

Direct conversion of glycerol into bio-oil via hydrotreatment using supported metal catalysts

Hydrotreatment of glycerol (a byproduct of bio-diesel production) was conducted in the presence of a number of different supported metal catalysts at a temperature of 300 C under 5 MPa initial pressure of H2. The bio-oil products were comprehensively characterized to determine their physical/chemical properties. Experiments with supported catalyst metals revealed a positive correlation between support acidity and bio-oil yield. It was determined that MoCoP is the most effective combination of catalyst metals, and the bio-oil yield from hydro-treatment of glycerol with the MoCoP catalysts is strongly dependent on the support materials, following the trend of MgO < AC < Al2O3 < zeolite. With the MoCoP/zeolite catalyst, a maximum yield of ?40 wt.% bio-oil, and >90% glycerol conversion was achieved for 60 min reaction. The volatile components of the bio-oil were found to consist mostly of substituted phenols and ketones in the C6-C9 range. The bio-oils obtained had a maximum HHV of 33 MJ/kg and the majority (?95%) of the compounds present was found to have boiling points lower than 165 C, making these bio-oils potential oxygenated fuel additives.

Gold-Catalyzed Controllable C2-Functionalization of Benzofurans with Aryl Diazoesters

A ligand-controlled gold-catalyzed chemoselective C2-functionalization of benzofuran substrates with aryl diazoesters has been developed. The use of IPrAu(PhCN)BArF provides unprecedented dearomatization products bearing a newly formed carbon-carbon double bond at the C2 position of benzofurans. In contrast, the C2-alkylation products have been isolated as the major products for phosphite gold catalysis.
