  Direct Asymmetric Michael Addition to Nitroalkenes: Vinylogous Nucleophilicity under Dinuclear Zinc Catalysis

  摘要：

  Under dinuclear catalysis, the direct conjugate addition of 2(5H)-furanone to nitroalkenes involves the gamma-position of the nucleophile. The synthetically versatile Michael adducts are prepared in good yields, with high levels of diastereo- and enantioselectivity. A model is presented to rationalize the observed stereoselectivity.

  The first organocatalytic Mukaiyama-Michael addition of 2-trimethylsilyloxy furan to nitroalkenes was promoted by Bronsted acids under solvent-free conditions. The conjugate addition took place in moderate to good yields with variously substituted nitroalkenes. The procedure is operationally simple and no workup is required.

• Inverting the Diastereoselectivity of the Mukaiyama–Michael Addition with Graphite-Based Catalysts

  Here, we show that graphite-based catalysts, mainly graphite oxide (GO) and exfoliated GO, are effective recyclable catalysts for a relevant stereoselective Mukaiyama-Michael addition, outperforming currently available catalysts. Moreover, the graphite-based catalysts described here invert the diastereoselectivity relative to that observed with known catalysts, with the unprecedented large prevalence of the anti diastereoisomer. This inverted diastereoselectivity is increased when the catalyst concentration is reduced and after catalyst recycling. Density functional theory calculations suggest that the selectivity is determined by two types of supramolecular interactions operating between the catalyst and the substrates at the diastereoselectivity-determining transition state, specifically, the pi-stacking of beta-nitrostyrene with graphite and the van der Waals interaction between the SiMe3 group of the silyl ether and the graphite.
