Enantioselective synthesis of β-trifluoromethylated pyrrolines has been developed by the organocatalyzed-conjugated addition of nitromethane to β-trifluoromethylated enones, followed by a nitro-reduction/cyclization/dehydration sequence in a one-pot procedure with 97â98% ees.
通过将硝基甲烷与δ-三氟甲基化烯酮进行有机催化-共轭加成,然后通过硝基还原/环化/脱水顺序,以97%-98%的对映选择性合成了δ-三氟甲基化吡咯烷。
