    A Convenient Samarium-Promoted Synthesis of Aliphatic (E)-Nitroalkenes under Mild Conditions
    摘要:
    A samarium-promoted synthesis of (E)-nitroalkenes from 1-bromo-1-nitroalkan-2-ols in high yields and with total selectivity is reported. This reaction together with the easy and efficient preparation of the 1-bromo-1-nitroalkan-2-ols constitutes a simple and advantageous alternative toward nitroalkenes with total E-stereoselectivity. A mechanism is proposed to explain the E-stereoselectivity of the beta-elimination reaction.

    -Bromonitroalkanes are efficiently reduced into the corresponding dehalogenated products in excellent yields with indium metal in the presence of a palladium(0) catalyst and indium(III) chloride in aqueous medium. The addition of bromonitromethane to carbohydrate-derived aldehydes or imines, followed by debromination of the intermediate bromonitro compounds represents an extremely efficient method for the
    (0)催化剂和氯化铟(III)的存在下,在性介质中,gem-硝基烷烃以优异的收率与属有效还原成相应的脱卤产物。将硝基甲烷添加到碳水化合物衍生的醛或亚胺中,然后对中间体硝基化合物进行脱,这是一种非常有效的立体选择性制备亚硝糖的方法。

    [Structure: see text] A catalytic NaI-mediated novel synthesis of 1-bromo-1-nitroalkan-2-ols was carried out by reaction of bromonitromethane with a variety of aldehydes, under very mild conditions. When the reaction was performed with chiral N,N-dibenzyl alaninal, the corresponding enantiopure (1S,2S,3S)-3-dibenzylamino-1-bromo-1-nitrobutan-2-ol was obtained with good stereoselectivity. The structure

    Highly enantiomerically enriched 2-bromo-2-nitroalkan-1-ols are prepared by direct condensation of aliphatic and aromatic aldehydes with bromonitromethane in the presence of a catalytic amount of copper(II) acetate and a C1-symmetric camphor-derived amino pyridine ligand.
