This protocol provides excellent chemical yields (up to 93%) of chiral 5-methyl-4-(2-nitro-1-arylethyl)pyrazol-3-ol derivatives with high enantioselectivities (up to 97% ee).eninfo:eu-repo/semantics/closedAccesschiral squaramide catalystsenantioselective synthesisMichael additionpyrazolonesEnantioselective conjugate addition of pyrazolones to nitroalkenes catalyzed by chiral squaramide organocatalystArticle33310611410.1002/chir.23295334288002-s2.0-85099191457Q2WOS:000606635800001Q3
