RT Journal Article T1 Gold(I)-Catalyzed Intermolecular Cycloaddition of Allenamides with α,β-Unsaturated Hydrazones: Efficient Access to Highly Substituted Cyclobutanes A1 Bernal Albert, Paloma A1 Faustino, Hélio A1 Gimeno, Ana A1 Asensio, Gregorio A1 Mascareñas Cid, José Luis A1 López García, Fernando K1 Gold K1 Catalysis K1 Cycloaddition K1 Allenamides K1 Cyclobutanes K1 Hydrazones AB α,β-Unsaturated N,N-dialkyl hydrazones undergo a mild [2 + 2] cycloaddition to allenamides when treated with a suitable gold catalyst. The method, which represents the first application of N,N-dialkyl hydrazones in gold catalysis, iscompatible with a wide variety of substituents at the alkenyl moiety of the hydrazone component, proceeds with excellent levels of regio- and diastereoselectivity, and provides densely substituted cyclobutanes with good to excellent yields PB American Chemical Society SN 1523-7060 YR 2014 FD 2014-11-19 LK http://hdl.handle.net/10347/12379 UL http://hdl.handle.net/10347/12379 LA eng NO Bernal-Albert, P., Faustino, H., Gimeno, A., Asensio, G., Mascareñas, J.L. and López, F.
