Design, synthesis and evaluation of organocatalysts in 1,4-conjugate additions to nitroolefins and alkylidene malonates
A family of cinchona-based and thiourea pyrrolidine-based organocatalysts were synthesised and fully characterised. Their catalytic activity and selectivity in 1,4-conjugate additions involving the Michael acceptor, nitrostyrene, was evaluated. Thiourea catalysts based upon the cinchona alkaloid …

EXPLORING NOVEL SUSTAINABLE SYNTHETIC METHODOLOGIES WITH NITRO COMPOUNDS
… study of four different topics, the reduction of nitroolefins employing ammonia borane as reductant, the enantioselective reduction of β,β-disubstituted nitroalkenes in deep eutectic solvents, the preliminary investigation of other enantioselective nitroalkenes reductions catalyzed by chiral …

Novel sulfur containing electrophiles in asymmetric organocatalysis
… be not very reactive and little similarities to nitroolefins can be postulated. We were able to obtain SMA-products with generally good yields and with enantiomeric excesses up to 64%. We observed that with the increase of enantioselectivity the reaction rate decreased. We also observed that more …
