The hyperbaric aza-Michael addition of mono- and diamines on α,β-unsaturated β,β-disubstituted mono- and diesters has been studied. While in the case of monoester, this reaction provides a β-aminoester presenting a quaternary center, a direct and efficient access to diester or lactams featuring an azanorbornyl skeleton was obtained when starting from a diester, following an unprecedented double aza-Michael
研究了在α,β-不饱和β,β-二取代的单-和二酯上单胺和二胺的高压氮杂-迈克尔加成反应。在单酯的情况下,该反应提供了一个代表季铵盐中心的β-氨基酯,而在从二酯开始进行前所未有的双氮杂-迈克尔加成反应后,从二酯开始可直接有效地获得具有二氮杂降冰片烯骨架的二酯或内酰胺。
