α-Branched aryl acetaldehydes are efficiently activated by a cinchona based squaric acid-derived peptide to provide, upon reaction with nitroolefins, 2,2,3-trisubstituted syn γ-nitroaldehydes with high diastereo- and enantioselectivity.
α-支链芳基乙醛被金鸡纳基方酸衍生肽有效活化,在与硝基烯烃反应后,提供具有高非对映选择性和对映选择性的2,2,3-三取代的顺γ-硝基醛。
