convenient method for the preparation of functionalized β-nitroalkenes based on the nitration of α,α-di- and α,α,β-trisubstituted unsaturated aldehydes, ketones and esters with tetranitromethane in the presence of triethylamine is described. Series of substituted β-nitroalcohols and β-nitroalkenes are obtained in good yields under mild conditions.
描述了一种方便的方法,该方法基于在三乙胺存在下用四硝基甲烷硝化α,α-二-和α,α,β-三取代的不饱和醛,酮和酯的方法来制备官能化的β-硝基烯烃。在温和条件下以高收率获得一系列取代的β-硝基醇和β-硝基烯烃。
