  dioxinone-derived silyl ether to nitroalkenes is reported. The conjugate addition is performed in absence of any catalyst under solvent-free conditions, proceeding with satisfactory efficiency with variously substituted nitroalkenes.Moreover, the first organocatalyzed Mukaiyama-Michael vinylogous reaction of trimethylsilyloxyfuran to nitroalkenes is described.The reaction is promoted by Brønsted acids under

  furan-2(5H)-one to (E)-(2-nitrovinyl)benzene catalyzed by a dinuclear Zn-complex. The relative configurations of the diastereomeric products were assigned by comparing NMR experimental chemical shift data with those computed by DFT methods. Corrected mean absolute error (CMAE) and CP3 analyses were used to compare the data sets. The absolute configuration of each diastereomer was initially assigned by

  在目前的工作中，我们描述了在双核锌配合物的催化下，通过呋喃-2(5H)-酮与(E)-(2-硝基乙烯基)苯的对映选择性迈克尔加成来制备两种非对映体。通过将 NMR 实验化学位移数据与 DFT 方法计算的数据进行比较，确定非对映体产物的相对构型。使用校正平均绝对误差 (CMAE) 和 CP3 分析来比较数据集。每个非对映异构体的绝对构型最初是通过电子圆二色性（ECD）数据分析确定的，这与相关反应产物的已知X射线晶体结构一致，即（R）-5-（（ R)-1-(4-氯苯基)-2-硝基乙基)呋喃-2(5H)-一。
• 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.
