A synthesis of aziridine esters based on the cyclisation of amino selanyl esters induced by the selanyl group activation was developed with either the Meerwein salt or NBS. Two asymmetric approaches are proposed: the diastereoselective reductions of α-selanyl β-iminoesters derived from α-oxoesters, which lead to cis chiral aziridine esters 6 and 6′; and the diastereoselective conjugate additions of
用Meerwein盐或NBS开发了基于由硒基活化引起的氨基硒基酯环化的氮丙啶酯的合成方法。提出了两种不对称方法:衍生自α-氧代酯的α-硒基β-亚氨基酯的非对映选择性还原,产生顺式手性氮丙啶酯6和6 ';并且将手性酰胺非对映选择性共轭加成到α,β-不饱和酯上,从而提供反式手性氮丙啶酯6和6 ''。
