Diastereospecific Synthesis of cis-β-Lactams (6a-g) has been achieved in ketene-imine cycloaddition reaction (Staudinger reaction) by using homochiral ketene precursors 3 and 4 derived from Oppolzer sultam, in very good yields.
通过使用来自Oppolzer sultam的同手性烯酮前体3和4,在烯酮-亚胺环加成反应(施陶丁格反应)中实现了顺式-β-内酰胺(6a-g)的非对映特异性合成,收率很高。
