imines derived from (+)-(1S,2S)-2-amino-1-phenylpropan-1,3-diol furnished cis-β-lactams stereoselectively on the Staudinger reaction. These homochiral cis-β-lactams were converted in to cis-β-lactams possessing aminol side chain at C-4. These aminols were efficiently transformed in to novel 4-cyano-cis-β-lactams, 4-acetoxy-β-lactam (which are well proven starting materials in the synthesis of carbapenem
由(+)-(1S,2S)-2-氨基-1-苯基丙烷-1,3-二醇衍生的亚胺在施陶丁格反应上立体选择性地提供了顺式-β-内酰胺。这些同手性顺式-β-内酰胺被转化为在C-4具有氨基侧链的顺式-β-内酰胺。这些氨基被有效地转化为新型的4-氰基-顺-β-内酰胺,4-乙酰氧基-β-内酰胺(在合成碳青霉烯抗生素中被广泛证明的起始原料)和用于合成β-羟基的先进起始原料。天冬氨酸。
