  • Iridium-Catalyzed Enantioselective Hydrogenation of Unsaturated Heterocyclic Acids
    作者:Song Song、Shou-Fei Zhu、Liu-Yang Pu、Qi-Lin Zhou
    DOI:10.1002/anie.201301341
    日期:2013.6.3
    binding: A highly enantioselective hydrogenation of unsaturated heterocyclic acids has been developed by using chiral iridium/spirophosphino oxazoline catalysts (see scheme; BArF−=tetrakis[3,5‐bis(trifluoromethyl)phenyl]borate, Boc=tert‐butoxycarbonyl). This reaction provided an efficient method for the preparation of optically active heterocyclic acids with excellent enantioselectivities.

    日期:——
    Electrochemical carboxylation of lactone enol triflates in DMF containing a catalytic amount of NiBr2·bpy with a platinum cathode and a magnesium anode under an atmospheric pressure of CO2 gave the corresponding cyclic α-alkoxyl-α,β-unsaturated carboxylic acids, captodative cycloalkenes, in good yields.

    日期:2017.11.9
    The gold-catalyzed oxidation of N-tosyl-protected 6-alkynyl-3,4-dihydro-2H-pyridines was studied in detail to obtain divinyl ketones in which one of the double bond is embedded in a heterocyclic framework. The best reaction conditions were then extended to different types of substrates to assess the scope of the reaction. DFT calculations were exploited to gain insight into the regioselectivity and

    作者:Laura Bartali、Antonio Guarna、Paolo Larini、Ernesto G. Occhiato
    DOI:10.1002/ejoc.200601089
    日期:2007.5
    carbonylative Suzuki–Miyaura cross-coupling reaction of enol triflates with alkenylboronic acids for the synthesis of unsymmetrical dienones is reported. Conditions were found that enabled the coupling of structurally different enol triflates derived from lactams, lactones, and thiolactones (i.e., cyclic ketene aminal, acetal, and thioacetal triflates, respectively) with various alkenylboronic acids at
