An efficient and simple strategy has been developed to synthesize various substituted nitroalkenes involving a cooperative catalytic system of FeCl 3 and piperidine. This dual catalytic protocol simultaneously activates both electrophile and nucleophile and works under mild reaction conditions so that many sensitive functional groups were tolerated. Moreover, this cooperative catalytic reaction is also suitable for various one-pot reactions involving nitroalkenes such as, 2H-chromenes, N-arylpyrrole and Michael reaction with indole. Notably, this method is low-cost, efficient and environmentally friendly. Copyright

experimental part, p. 2980 - 2984 (2012/07/28)
The utility of nickel hydroxyapatite nanocomposite (Ni-HAp) as a green catalyst for solvent free, microwave-assisted Henry reaction using nitromethane and a series of aromatic aldehydes as substrates is presented. The selected catalyst performed well to afford the respective nitrostyrenes which were quantified by gas chromatography equipped with a mass spectral detector (GC-MS). A few of the products were identified from the respective nuclear magnetic resonance (NMR) spectral data.

A mild and efficient [3+2] nitrile oxide/olefin cycloaddition provided a rapid and convergent entry into precursors of bisphenolic spiroketals, a structural type unique to the rubromycin family of natural products. In addition, implementation of the premi

The hypervalent iodine oxidation of phenol derivatives bearing aminoquinones at the ortho (9) or meta positions (19) in 2,2,2-trifluoroethanol was investigated with the aim of preparing novel antitumor compounds. Azacarbocyclic spirodienone derivatives (13) or phenol derivatives containing the 2,3-dihydro-1H-azepine systems (17, 20) were selectively obtained by the reaction of these phenol derivatives and the hypervalent iodine reagent, phenyliodine(III) bis(trifluoroacetate). The application of this reaction to phenol derivatives bearing aminoquinones (10-12) is also described.
