An enantioselective synthesis of γ-nitroesters by a one-pot asymmetric Michael addition/oxidative esterification of α,β-unsaturated aldehydes is presented. The procedure is based on merging the enantioselective organocatalytic nitroalkane addition with an N-bromosuccinimide-based oxidation. The γ-nitroesters are obtained in good yields and enantioselectivities, and the method provides an attractive
提出了通过对α,β-不饱和醛的一锅式不对称迈克尔加成/氧化酯化反应对γ-硝基酯的对映选择性合成。该程序基于将对映选择性有机催化硝基烷烃加成与基于N-溴琥珀酰亚胺的氧化合并。以良好的产率和对映选择性获得γ-硝基酯,并且该方法为旋光性γ-氨基酯,2-哌啶酮和2-吡咯烷酮提供了有吸引力的入口。
