of nitro‐functionalized α,β‐unsaturated esters has been prepared by a regio‐ and diastereoselective Michael addition of nitroalkanes to β‐nitroacrylates, performed at room temperature, under carbonate on polymer as promoter, and in the presence of ethyl acetate as eco‐friendly solvent. Moreover, by the modular choice of the reaction conditions the method allows the synthesis of 1,3‐butadiene‐2‐carboxylates
在室温下,在碳酸酯作为助催化剂的聚合物上,在室温下,通过将硝基烷烃进行区域和非对映选择性迈克尔加成到β-硝基丙烯酸酯中,制备了一类新型的硝基官能化的α,β-不饱和酯。作为环保溶剂。此外,通过模块化选择反应条件,该方法可以合成1,3-丁二烯-2-羧酸盐。
